Kate Bosworth

Topshop has launched its festival collection inspired by Kate Bosworth, which plays into the brand's multidimensional, interactive Summer campaign. From the acid-washed denim dresses and buckle-strap wedges, to the pink-dipped feather angel wings and silver slipdress (made for frolicking), the lineup has Bosworth's mark on every piece.

"To gain learning experience from the Topshop design team has been a great opportunity for me. Our intent was to create fresh, wearable, and effortless festival pieces. I am proud of our work together and I adore these pieces," Bosworth said. Along with the collection debut, a short film shot by Bosworth's fiancé, Michael Polish, entitled "The Road to Coachella," was released today, too. The dreamy video reveals Kate Bosworth roaming Mono Lake, CA in a handful of effortlessly styled Topshop looks.

Kate Bosworth showed skin in a backless ensemble for the premiere of her latest film, Black Rock, in Hollywood last night. She was accompanied by her costars Lake Bell and Katie Aselton for the festivities. Ed Helms also made an appearance at the premiere for the film, which debuted at the Sundance Film Festival back in January and will be released in the US next Friday.

It has been a big week for Kate, who jetted back to the West Coast for her premiere following a Met Gala appearance on Monday in NYC. Kate donned a pink Balmain dress and was joined by her fiancé, Michael Polish, for fashionable festivities in the Big Apple earlier this week. Don't forget to vote for Kate in our POPSUGAR 100 bracket for a chance to win a Victoria Beckham handbag!

The Met Gala is tonight, and the style set has already descended upon NYC in preparation of fashion's biggest event. And last night's party scene is proof (times three) that we're in for a jam-packed red carpet come Monday. To toast Dolce & Gabbana's Fifth Avenue flagship store opening, Gisele Bündchen, Kylie Minogue, and Stacy Keibler all stepped out in the label's sexy cocktail fare. Not to be outdone, Moda Operandi and Net-a-Porter both held swanky affairs, playing host to the likes of Karolína Kurková, Kate Bosworth, and a polka-dot-clad Miranda Kerr. It was, to say the least, an evening of epic style proportions. See who wore what on the pre-Met Gala party scene, right this way.

Kate Bosworth and Demi Lovato helped launch the new Topshop/Topman store at The Grove in LA yesterday. Kate wore head-to-toe Topshop as she assisted in cutting the ribbon for the store's opening, while Demi wore a studded leather jacket — to match her studded foot cast — as she took the stage to perform for fans. This is the second Topshop event that the two celebrities have attended this week. On Wednesday, Demi and Kate partied for Topshop with Julianne Hough, Ryan Seacrest, and Kim Kardashian.

The Topshop events come as Demi's future with The X Factor is in question. Demi recently admitted that she hasn't been asked back officially, but she would sign on for another season. She also said that she would love to see Lady Gaga replace Britney Spears, who announced that she was leaving the show back in January.

Mulberry has been a British brand favourite for over 40 years due to it's innovative, trend-setting fashions and of course, legendary supple leather products. With a long-standing reputation like that, it's no wonder that Mulberry has taken the fashion set by storm in America too. Stars like January Jones, Kate Bosworth and Lily Collins have all been spotted in the past week wearing clothing and handbags designed by Emma Hill. Take a closer peek at their celebrity style here and let me know what you think of their Mulberry ensembles in a comment below.

Kate Bosworth and her fiancé Michael Polish premiered and promoted the film that brought them together, Big Sur, at the Sundance Film Festival on Tuesday. Michael directed the movie, which is an adaptation of Jack Keroauc's book of the same name, and Kate stars in it as one of Jack's lovers. Kate and Michael met while making Big Sur, and the actress revealed that she fell in love with Michael first as a director before their romantic relationship started. Kate also celebrated her 30th birthday in early January and spoke to press about taking on more mature roles like this one as she enters the next big decade of her life and career.

Kate Bosworth and Naomi Watts hit the black carpet at last night's Audi Golden Globes kickoff bash in LA. The get-together marked the end of a big weekend for Naomi, who picked up an honor at Saturday's Palm Springs International Film Festival gala.

Kate and Naomi mingled among a star-studded crowd that included Modern Family buddies Eric Stonestreet and Julie Bowen, as well as Bryan Cranston, Louise Roe, and Jamie Chung.

Kate Bosworth, in white Emilio Pucci, hit the red carpet in NYC last night to celebrate the launch of the Target + Neiman Marcus Holiday Collection with Zoe Saldana.

Even the special guests had to wait in line to get their hands on the goods — we caught Kate at the register at the end of the night!
