The private bash was attended by A-listers like Katy Perry, Leonardo DiCaprio and Rihanna.
Following last year's epic bash, the power couple hosted another post-Oscars soiree at the swanky Chateau Marmont in West Hollywood, California, on Sunday.
The tremendously private party was invite-only and brought out A-list stars like Drake, Leonardo DiCaprio and Rihanna, who pulled out all the stops with a sexy off-the-shoulder leopard-print dress by Alexandre Vauthier and ankle-strap heels. A source told ET that invited guests were "only told the location mere hours before the event," and were asked to arrive through a discreet entrance at the hotel's garage, which was transformed into a chic late-night lounge setting.
Plenty of couples arrived in style, including Katy Perry and Orlando Bloom. The newly engaged lovebirds were spotted walking into the soiree hand in hand, with Bloom in a black tuxedo and Perry in a ruffled, one-shoulder gown.
Jennifer Lopez and Alex Rodriguez, Chrissy Teigen and John Legend, Jason Momoa and Lisa Bonet, Ciara and Russell Wilson, and Joe Jonas and Sophie Turner were other couples in attendance, all wearing the same ensembles they rocked to the Vanity Fair party earlier in the night. According to our source, everyone was told that no photos were permitted inside the bash and that "what happens in the garage, stays in the garage."
Inside the party, they were treated to delicious cooking from Daniel Humm of Eleven Madison Park, along with an abundance of JAY-Z's Armand de Brignac (Ace of Spades) Brut Gold champagne. There was also caviar, an extravagant raw bar, fried chicken and waffles, truffle potato quesadillas and a delicious egg sandwich with cheddar and beef sausage. Additionally, the source says a surprise pizza pop-up window from New York City's Pasquale Jones featured slices and pies for guests to enjoy all night long.
Other guests included Sean "Diddy" Combs, Serena Williams, Paul Rudd, Emilia Clarke, Chris Evans, Kobe Bryant, Regina King, Taraji P. Henson, Taron Egerton, Jourdan Dunn, Tiffany Haddish, Jamie Foxx, Usher, James Corden, Aziz Ansari, Ellen Pompeo, Winnie Harlow, Vin Diesel, Natalie Portman, Nas, Michael B. Jordan, Angela Sarafyan, Gemma Chan, Tessa Thompson, Chadwick Boseman, Dave Chappelle, Adam Driver, Jeremy Meeks, Spike Lee and Olivia Colman.
