Miley Cyrus put the never-ending breakup rumors to rest when she put her engagement ring on display while walking the red carpet at the Maxim Hot 100 party at Create nightclub in LA last night. She wore a Valentino jumpsuit and flashed her bauble, which has been the subject of a lot of speculation after rumors surfaced in March that her relationship with Liam Hemsworth was on the rocks. Since the gossip began, Miley has been spotted not wearing her ring, and she ditched her bling when she attended the 2013 Met Gala earlier this month. However, she could have forgone the accessory in order to maintain her Marc Jacobs punk look, which featured several big rings.

Engagement rings aside, Miley has had a busy Spring so far. She earned the top spot on Maxim's Hot 100 list, which she celebrated by taking part in a sexy photo shoot. Miley is also focused on her upcoming new album and has been tweeting photos of herself in the recording studio. She also teased that she will make a "special announcement" at the Billboard Music Awards this Sunday.

Armed with iPhones, American girls have come out in droves to spot Prince Harry, who wraps up his US tour today. The man third in line to the British throne (that is, until Kate Middleton has her baby) has been participating in loads of all-American activities. He's mingled with cheerleaders, tested out his American football skills, played baseball in New York City, spent time with First Lady Michelle Obama and military families, and sang happy birthday to Olympic gold medalist and adorable teen Missy Franklin. Much of that time, Prince Harry has had an audience of "Harry hunters," the unofficial term given to wide-eyed girls who aspire to be Kate's sister-in-law one day, if only in their dreams. Before Harry hops back across the pond, let's send him off with a look at all the admiring female fans who came out for his visit.

Kerry Washington teamed up with her fellow ABC stars for a special bash to celebrate the upfronts in NYC last night. She wore a red Marc by Marc Jacobs leather dress as she walked the black carpet alongside stars like Rebel Wilson, Hayden Panettiere, and the Modern Family cast. Hayden wore a purple Herve Leger dress and flashed a diamond ring inside the bash with boyfriend Wladimir Klitschko. However, despite persisting rumors that Hayden is engaged to Wladimir, she wore the ring on her right hand, not on her engagement ring finger.

Kerry's been preparing for the season finale of Scandal, which airs on Thursday. She stopped by Ellen to promote the episode, which she says ends with a "crazy" cliffhanger. Kerry added, "The season finale — the very last line of the episode, I almost couldn't get it out of my mouth."

Kate Moss dressed down in a suede jacket adorned with fringe to show her support for her close pal, famed photographer David Bailey, during a charitable evening out at the Bulgari Hotel in London last night.

The event, which was hosted by David, included a charity auction benefiting Marie Curie Cancer Care to celebrate the launch of the Samsung Smart Camera NX300. Kate switched gears to friends after kicking off the week with family. On Sunday, Jamie Hince's parents, Carole and William, visited the Cotswolds, and the foursome stepped out for lunch.

Leonardo DiCaprio suited up to join his The Great Gatsby leading lady, Carey Mulligan, to kick off the Cannes Film Festival with a glamorous photocall for their film today. Leo and Balenciaga-clad Carey were joined by the rest of their costars, Isla Fisher, Tobey Maguire, Joel Edgerton, as well as the film's director, Baz Luhrmann, as the annual festival got under way in the South of France. It was a busy day for the Gatsby crew, who also participated in a press conference to discuss the film that opened in the US last Friday. Gatsby will make its European premiere tonight in Cannes. The Great Gatsby boasted impressive numbers in its first week, raking in $51.1 million from its US debut.

Leo and his longtime friend Tobey Maguire were reunited at the festival after pairing up earlier this week in NYC. Tobey showed his support at Leonardo's Christie's auction, which raised $35 million to benefit environmental and wildlife conservation efforts, a cause that is backed by the Leonardo DiCaprio Foundation.
