Katie Holmes filmed scenes for Spike Lee's latest producing project, Mania Days, in NYC yesterday. She started working on the movie late last month but was joined by costar Luke Kirby on Tuesday. The duo shot scenes in front of a church, held hands while walking on the sidewalk, and got caught up in fits of laughter. In the film, Katie and Luke play two manic depressives who find each other in a psychiatric hospital and develop a romance centered on their conditions.

Katie was in a different kind of spotlight last week when she made a stunning Met Gala red carpet appearance. The actress will remain in front of the cameras for a while, though, since she's also tied to another romantic comedy, Responsible Adults, alongside Chace Crawford.

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. Kate's relationship with David dates back many years, since she has posed for the highly regarded British photographer on multiple occasions over her modeling career. 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.

Reese Witherspoon and Jim Toth shared a laugh while dining alfresco at the SoHo House in NYC yesterday. Jim enjoyed a glass of wine while Reese skipped the alcohol and drank water during the meal. The couple spent the day together, running errands and stopping by a C. Wonder store to get in a bit of shopping. Reese and Jim took their trip to the Big Apple after the actress wrapped up filming for The Good Lie in Atlanta. Reese debuted her new blond hairdo when she returned to the couple's home base in LA over the weekend to spend time with her family. She may be getting in a break before she returns to her busy work schedule. Reese recently signed on for Three Little Words, a new film directed by James Mangold. She is also preparing to film Wish List and Men Are From Mars, Women Are From Venus later this year.
