Robert Downey Jr

Gwyneth Paltrow hit the red carpet in a sheer colorblocked Antonio Berardi dress at the premiere of Iron Man 3 in LA yesterday. She was joined by her castmates Guy Pearce, Ben Kingsley, Don Cheadle, and Robert Downey Jr., who brought along his wife, Susan. The couple arrived sporting dark sunglasses on the carpet and squeezed in some sweet PDA while waving to fans. Last night's event marks the first stateside premiere ahead of the movie's May 3 release. When asked if there would be a fourth Iron Man movie, or if he has plans to appear in the Avengers sequel, Robert said he "doesn't want to wear out [his] welcome" as Tony Stark but knows there's a lot of goodwill for the franchise and his character. Gwyneth and RDJ have recently been promoting the action flick overseas, including stops in Munich, Paris, and London. Gwyneth told us that while across the pond, she took her kids, Apple and Moses, to see the movie with their friends and "they loved it."

It's been a busy month for the actress, but with lots of cause for celebration. In addition to making the press rounds for the third installment of Iron Man, Gwyneth's second cookbook, It's All Good, debuted at number one on the New York Times bestseller list earlier this month. Gwyneth was also named People magazine's Most Beautiful Woman this week. In the issue, Gwyneth revealed that despite glamming it up for the red carpet, she's much more stripped-down while hanging out at home, saying, "Around the house, I'm in jeans and a t-shirt. I don't really wear makeup."

Gwyneth Paltrow, in a Dior dress, and Robert Downey Jr. got flirty for a photocall in London today. The Iron Man 3 costars popped up in the UK for the latest stop on their worldwide tour, which has also taken them to Germany and Paris. Gwyneth and RDJ arrived in London during a somber time, as former British Prime Minister Margaret Thatcher was laid to rest today. They will be extending their stay across the pond since the film's UK premiere was pushed back from its originally scheduled date, today, to tomorrow due to the funeral arrangements, which required heightened security to tend to the large crowds.

Gwyneth and RDJ have been turning on the charm during the film's press push, and Robert planted kisses on Gwyneth's cheek during their photocall in Munich last week. The duo will continue the fun into next week as they are scheduled to head back to the US to premiere Iron Man 3 in LA ahead of its May 3 release.

Robert Downey Jr. and Gwyneth Paltrow posed together during their Iron Man 3 photocall at Le Grand Rex theater on Sunday night in Paris. Gwyneth was decked out in head-to-toe florals by English designer Erdem. It's their second stop together on a short European tour. Last week saw the duo in Munich, where Gwyneth wore KaufmanFranco to a German event. Next week, it's back to the UK for Gwyneth. She and Robert will attend Iron Man 3's London premiere Thursday, April 18. The red carpet screening had originally been scheduled for Wednesday but was pushed one day back to make allowances for crowds expected in the capital due to Margaret Thatcher's funeral.

Gwyneth Paltrow donned a white Kaufmanfranco dress to join her Iron Man 3 costar Robert Downey Jr. for a photocall in Munich this morning. He caused quite a stir as he chose to wear traditional Bavarian garb of lederhosen for the occasion. Today's stop marks Gwyneth's first on the film's worldwide promotional tour. However, the action has already begun for RDJ with stops in Korea, Beijing, and Moscow. The pair are next headed to Paris to debut the film on Monday, followed by stops in London and LA leading up to Iron Man 3's May 3 release in the US.

Gwyneth is now switching gears to promote her latest big-screen endeavor following a recent press push for her new cookbook, It's All Good. As if taking on double-duty with her film and new book were not enough, Gwyneth also graces the cover of Harper's Bazaar's May edition, and inside the issue, she spoke about her evolving marriage to husband Chris Martin. She said, "We are growing into very similar people. It's cool, it's good. It's not always easy, though!"

The Avengers is already shattering records at the box office, but you can still re-live the fun (or get another glimpse), with even more new stills from the film. Get another peek at the film's familiar faces — that is, Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Chris Hemsworth as Thor, Scarlett Johansson as Black Widow, and Samuel L. Jackson as Nick Fury.

Scarlett Johansson, Robert Downey Jr., and the rest of the all-star Avengers cast stepped out in London tonight for the UK premiere. The actors are making their way around the globe prior to the May 4 US release of the action adventure. We were on hand for the LA debut last week, and since then, Scarlett, RDJ, and the rest of the celebs have been on the road talking up their larger-than-life flick. It was a special evening for dad-to-be Chris Hemsworth, who was joined by his Hoss Intropia-clad wife, Elsa Pataky. The couple are expecting their first child this Summer, though they've decided to keep the baby's gender a secret. Robert might be able to give Chris some parenting tips — RDJ and his wife, Susan, welcomed son Exton in February.

Scarlett opted to break away from the sexy LBDs she's been wearing and instead chose a floral embroidered Prada frock. Scarlett was the only female cast member to make the trek to Moscow for the Avengers screening, but tonight she was joined by her partner in fighting crime, Cobie Smulders. Cobie dazzled in a form-fitted, floor-length Alexandra Vidal red gown.

A Versace-clad Scarlett Johansson joined Robert Downey Jr., Chris Hemsworth, Samuel L. Jackson, and several other big superhero names at last night's premiere of The Avengers at the El Capitan Theatre in Hollywood. We were live on the red carpet, bringing you our interviews with the heroes of the new Marvel movie and capturing all the star-studded arrivals. The film's boldfaced cast also includes Mark Ruffalo, who had his lovely wife Sunrise Coigney on his arm at the debut, Tom Hiddleston, and Jeremy Renner, to name just a few. Stellan Skarsgård, who has a small role in the film, was also in attendance with his son Alexander Skarsgård close by.

On the carpet, Scarlett told us that if she had her character Black Widow's powers of interrogation, she'd probably use her skills to grill George Clooney for all his secrets. Meanwhile, new dad Robert Downey Jr., who was there with his wife Susan Downey, spoke about feeling great since the birth of their son Exton earlier this year. Stay tuned for today's PopSugar Rush to catch our interviews with Scarlett and RDJ, and for any others you may have missed!

The Avengers is one of the most anticipated movies of 2012, but the year's biggest box office hit — The Hunger Games — came up several times during the evening. Chris Hemsworth spoke about his little brother Liam Hemsworth's success with the blockbuster, and Jeremy Renner — whose character Hawkeye is an expert with the bow and arrow — told us he thinks he'd easily take Katniss in an archery competition.

This year's scariest films were honored in LA last night at the sixth annual Spike TV Scream Awards. Top prizes went to Harry Potter and the Deathly Hallows: Part 2 taking home six wins — get the entire list of Scream Awards winners here! Daniel Radcliffe couldn't make it to the show, which airs Tuesday night at 9 p.m., but he did join the fun via telecast to accept his statue for ultimate scream. Other winners included Black Swan's Darren Aronofsky for best director and Natalie Portman for fantasy actress. Bradley Cooper was still smiling from his date with Jennifer Lopez while accepting a statue for Limitless, and newcomer Chloë Moretz was triumphant in best horror actress for her haunting role in Let Me In. It was a big night for fan favorite True Blood, which scored top billing in the best ensemble category with hunks Joe Manganiello and Alexander Skarsgard taking home individual trophies. Colin Farrell presented Robert Downey Jr. with the hero award, and The Dark Knight Rises cast Anne Hathaway, Gary Oldham, and Joseph Gordon-Levitt took a break from filming to accept the most anticipated movie statue. Other hot actors and actresses handed out awards including Zoe Saldana, Kate Beckinsale, and Dylan Mcdermott while Nicolas Cage made a grand entrance to debut an exclusive world premiere clip of his upcoming Ghost Rider Spirit of Vengeance.

Jennifer Aniston joined actors Jack Black, Michael Douglas, Jon Favreau, and more at the American Cinematheque Awards in LA last night to honor her friend and fellow thespian Robert Downey Jr. Jennifer took the stage in a sexy, form-fitting gown to say a few kind words about her long-time friend RDJ. Jennifer joked, "[Robert] never let his career get in the way of his commitment to hard-core, classic Grade A drugs." Justin Theroux, who dined next to Jen at the event, also shares a connection to Robert, having penned the scripts for Tropic Thunder and Iron Man 2. Robert stopped by Jen and Justin's table to pose for a photo, but RDJ also stuck beside his wife and mom-to-be, Susan Downey. It's been an exciting week for Robert. In addition to last night's party, the first trailer for The Avengers was released.
