Paris Hilton, Miley Cyrus

A little bit of performance art, perhaps?

The massive celeb-studded party that is Art Basel Miami showed no signs of dying down last night (or this morning), with Miley Cyrus and Paris Hilton keeping the anything-goes action going by making out in the wee hours at E11EVEN, a cabaret/nightclub in South Beach, multiple sources tell E! News.

That's...hot? Actually, maybe the real surprise is that these famous scenesters haven't locked lips before!

Miley had her new beau, Patrick Schwarzenegger, with her and the trio stayed at the all-hours club until about 5:30 a.m.—about an hour after Miley was overheard saying she had no plans to go to bed that night.

Patrick and Miley kicked off the night the Moschino Barbie party in honor of creative director Jeremy Scott's self-titled first book. Hence Miley's eye-popping Moschino outfit! (Not that the bright-pink crop top and skirt trimmed in fluorescent green was her wildest ensemble of the week or anything...)

E!

The couple also made their way to at the Bootsy Bellows pop-up club at Shore Club, where she joined DJ Paul Oakenfold and Bootsy co-founder David Arquette in the DJ booth.

We're told that she and Patrick also hit the 1OAK and Up & Down pop-up at Rec Room before making themselves at home at E11EVEN.

Shoot, we could use a nap after just writing about that all that partying.
