Art Basel Ends: Who Was There and What They Did

— -- Art Basel, the four-day spectacle that explores all things art, drew a slew of celebrities, including Miley Cyrus and her beau, Patrick Schwarzenegger, Usher, Joe Jonas, newlywed Solange Knowles and the world’s fastest man, Usain Bolt.

Between gallery openings, the stars shopped, dined and partied in and around Miami.

Cyrus debuted a new original song during a performance at Art Basel Wednesday night. She told the audience that "The Twinkle Song" was inspired by her friend's dying cat, who spoke to her in a dream. According to Billboard, Cyrus also sang a duet with a topless woman and was joined by Wayne Coyne of the Flaming Lips.

Later, she partied with Schwarzenegger, Paris Hilton and rapper A$AP Rocky.

From the looks of her photos on Instagram, the star had a great time.

Hilton wasn't there just for the parties. The hotel heiress also had a job to do.

She brought along her younger sister, Nicky Hilton.

Later, Paris Hilton, an avid Barbie collector, came dressed as a life-sized version of the famous doll at a party Thursday night to celebrate designer label Moschino's collaboration with the Mattel toy company.

Compared to Hilton and Cyrus, Kim Kardashian cut a conservative figure in black.

The reality star was joined by friends Jonathan Cheban and former NBA star Scottie Pippen's wife, Larsa Pippen, at the Paper magazine dinner to celebrate her naked cover.

Joe Jonas attended the same event.

Fellow singer Usher also partied at Art Basel, with Zoe Kravitz and Leonardo DiCaprio.
