Longtime pals Jaden Smith and Kendall and Kylie Jenner were spotted walking around the museum, admiring the show. Earlier in the evening, Smith posed on the carpet holding his own blonde dreads, while Kendall and Kylie each stunned in their revealing gowns -- seriously, no one could get enough of Kendall flaunting her booty.

And the young Hollywood trio weren’t the only friends catching up. Blake Lively and Ryan Reynolds posed with Reynolds’ Life co-star Jake Gyllenhaal and actor Hugh Jackman for a dapper shot at dinner. Is it just us or is Wolverine giving Deadpool some sneaky side eye?

One couple that only had eyes for each other was Joe Jonas and Sophie Turner. Though the pair opted to walk the red carpet solo, they linked up for the event, strolling arm-in-arm through the museum before busting a move on the dance floor.

An unexpected duo who also showed off their moves were first-time attendees Celine Dion and Halle Berry. The legendary stars broke it down, letting loose for all to see.

It could be because they were listening to the vocal stylings of Katy Perry, who changed out of her red avant-garde Maison Margiela Couture gown and into a black latex ensemble for her performance. Perry rocked her new platinum buzz cut as she sang for the celebrity crowd.
