The fun wasn't over for the Met Gala 2013 attendees in NYC last night as they flocked to the Standard Hotel following the ball for the official afterparty at the Boom Boom Room. Madonna stripped out of her bum-baring Met Gala outfit and changed into a fishnet body stocking and black lacy lingerie to mingle with guests like Katy Perry, Allison Williams, and Frank Ocean. She wasn't the only star who made a costume change — Amanda Seyfried took off her gown and changed into a baggy black t-shirt to hit the dance floor with Frank. Meanwhile, Miranda Kerr met up with January Jones, Jennifer Lawrence arrived with Marion Cotillard, Gerard Butler mingled with Karolina Kurkova, andNicole Richie connected with Kirsten Dunst, and Mary-Kate Olsen snuggled with boyfriend Olivier Sarkozy. Mary-Kate and Olivier weren't the only couple at the late-night bash, as Jennifer Morrison was spotted holding hands with her Once Upon a Time costar Sebastian Stan and Kate Bosworth hugged Michael Polish.

Justin Timberlake welcomed his celebrity pals to a special show at NYC's Roseland Ballroom last night. The performance, which was organized to celebrate his new deal with MasterCard and billed as one of the credit card's "Priceless" events, brought out JT's SNL pals Andy Samberg and Jason Sudeikis. Justin's wife, Jessica Biel, was also in the wings cheering on her husband. Andy and Jason had their ladies too — they brought their respective fiancées, Joanna Newsom and Olivia Wilde. Also out for the performance were Julianne Hough, Uma Thurman, and Brooke Shields.

The Cinco de Mayo show gave Justin a chance to perform music from his latest album, The 20/20 Experience, which he recently announced will be followed up by The 20/20 Experience Part 2 in September. He sang plenty of his old songs too, from "Like I Love You" to "Cry Me a River" and "Senorita." Justin joked with the crowd, with quips like, "You're at an eight and a half. If you be honest with me, I'll be honest with you." He also asked, "Is anybody drunk yet?" After hearing some cheers, he added, "Good for you!" His frequent collaborator Timbaland emerged toward the end for a rendition of "SexyBack." It seems Justin had as great a time as the fans. He tweeted last night, "Thank you NYC and Roseland Ballroom! Had so much fun tonight. Lets do it again soon."

After last night's White House Correspondents' Dinner, Vanity Fair hosted its annual postparty with Editor in Chief Graydon Carter greeting the many celebrity guests. Nicole Kidman mingled with other actors including Jeremy Renner, Paul Rudd, and Nashville leading ladies Connie Britton and Hayden Panettiere. Despite being dubbed the "nerd prom," the many actresses in DC last night were dressed to the nines in their best gowns — check out who wore what on the White House Correspondents' Dinner red carpet.

The Vanity Fair bash, cohosted by Bloomberg, also brought out celebrity couples — Jason Sudeikis stuck close to fiancée Olivia Wilde, Sofía Vergara mingled with her own spouse-to-be, Nick Loeb, and Bradley Cooper brought his young model love, Suki Waterhouse. Jason made sure to say hi to his fellow SNL buddies from the past and present, including Fred Armisen and Amy Poehler. Sofía, meanwhile, hung out with pal Katy Perry.

Ryan Reynolds is in talks for a new thriller, Emma Stone signed on to be Woody Allen's next leading lady, and Kate Hudson and James Franco are headed to London for Good People. Meanwhile, Shia LaBeouf is in talks for not one but two new roles, and The Avengers baddie Tom Hiddleston is in early talks to lead a reboot of a cult classic.

Olivia Wilde and Jason Sudeikis celebrated their inner children when they visited Disneyland in Anaheim, CA, yesterday. The couple cuddled on a kids' ride and walked through the park with a Disney employee. Olivia and Jason also tried to lift Disneyland's famous Sword in the Stone, but were, like all parkgoers, unable to extract it.

The newly engaged couple are in California while Jason's show, Saturday Night Live, takes a short hiatus. Before they headed off to the Happiest Place on Earth, Olivia and Jason took in a show back in NYC when they attended the premiere of Breakfast at Tiffany's on Broadway.

Emilia Clarke channeled Audrey Hepburn's glamour when she premiered her new play, Breakfast at Tiffany's, on Broadway last night. She wore a sheer Dolce & Gabbana frock as she worked the red carpet alongside her costar Cory Michael Smith, who wore Balenciaga, and guests Jason Sudeikis and Olivia Wilde, who hugged and giggled at the theater. The play has been earning Emilia decent reviews, with one Huffington Post play critic admitting that while she doesn't fit the physical profile of Holly Golightly, she did a "more than acceptable job" living up to the iconic character.

Emilia was in the Big Apple for the event while her Game of Thrones costars were busy celebrating the third season premiere of their hit HBO show in San Francisco. She did get to squeeze in some time with her castmates earlier this week when she dropped by the LA premiere of Game of Thrones.

Olivia Wilde, Steve Carell, and Jim Carrey joined up to premiere The Incredible Burt Wonderstone in LA yesterday. Olivia wore a stunning black Gucci gown to pose for photos while her fiancé, Jason Sudeikis, bypassed the red carpet and headed straight into the event at the famed Chinese Theatre. Steve, meanwhile, posed with his wife, Nancy. Other celebrity attendees included magician David Copperfield, Melissa Joan Hart, and Steven Tyler.

The Hollywood debut comes just a few days after the cast flew out to Austin to screen the film at SXSW and less than 24 hours after Olivia Wilde's interview in Marie Claire came out. In the magazine feature, Olivia spoke about her relationship with Jason and her 2011 divorce from Italian aristocrat Tao Ruspoli. She said, "I'm so grateful for the pain and the heartbreak [from the divorce]. It gave me the courage to leave and brought me to the great love of my life."

Olivia Wilde and Jason Sudeikis were all smiles as they went for a walk through NYC yesterday. Olivia, who was in a leather jacket by Rag & Bone, recently let slip that she is considering having the couple's wedding in NYC, where the two share an apartment. She shared that a "New York wedding would be ideal. I don't know. I haven't had time to think about it." Olivia and Jason have been engaged since just after the holidays, but she admitted that they have been too busy with other projects to really start planning. She added, "Right now, I'm just enjoying being engaged."

Jason and Olivia have certainly been busy: Jason is currently in the middle of Saturday Night Live, which will welcome guest host Justin Timberlake this weekend. Meanwhile, Olivia has a slew of films in the works and also confirmed yesterday that she will be attending SXSW to premiere her new film Drinking Buddies with Anna Kendrick and New Girl's Jake Johnson.
