So long Anna Wintour, hello Rihanna! The party didn't end at the Metropolitan Museum of Art's Costume Institute Gala in NYC on Monday, May 5. Some of the biggest A-listers in Hollywood—including Bradley Cooper, Lupita Nyong'o, and Zooey Deschanel—made their way to Rihanna's star-studded bash at the Up & Down nightclub in the West Village to dance, grab a drink, and escape from the flashing camera lights. (The "official" after party was at the Boom Boom Room at the Standard, however, many opted to party longer at Rihanna's bash.)
The "Diamonds" singer, 26, slipped out of her red carpet Stella McCartney crop top and full-length skirt into a sexy gold ensemble for her night of festivities. Greeting her guests (with a little side boob and bum exposure) Rihanna stayed near the DJ booth for most of the night, until eventually heading downstairs to the photo booth.
An array of celebrities kicked their heels off at the NYC hotspot, which revealed some odd couplings and surprising pals. Dianna Agron, for instance, arrived ready to hit the dance floor with Gabrielle Union, Nyong'o, and American Horror Story's Sarah Paulson. Bravo's Watch What Happens Live! host Andy Cohen came piling in soon after with friends Nicole Richie, Kate Bosworth, Alexa Chung and Dakota Johnson.
Some stars decided to change out of their red carpet outfits, but all were greeted in the same way. As they entered the club, guests of Rihanna were given D'usse cocktails and were entertained by Jermaine Dupri's DJ skills.
Other stars in attendance included Leonardo DiCaprio, Selena Gomez, Suki Waterhouse, John Legend and wife Chrissy Teigen, Seth Meyers and wife Alexi Ashe, Janelle Monae, Naomi Watts, Chiwetel Ejiofor, Jessica Alba and husband Cash Warren, Ellen Pompeo, and Kristen Wiig. Rashida Jones, Paul Rudd and Ronan Farrow made their way in toward the end of the of the night.
Someone not checked off on the guest list? Rihanna's beau Drake. Although the rapper wasn't present, a source tells Us all is well with the couple.
"It's working well," a source told Us last month. "Drake is really different from what she's used to. He's so different from the guys she usually likes." The source added: "They really are good together."
