Miley Cyrus spotted making out with Paris Hilton at Miami club, source says

If anyone thought Miley Cyrus would tone down her wild ways now that she’s officially dating Maria Shriver and Arnold Schwarzenegger’s son Patrick, they were sorely mistaken.

The former Disney sweetheart was spotted club hopping in Miami on Thursday night with her beau, making stops at hotspots like the Bootsy Bellows pop-up at Shore Club and 1OAK at Rec Room before they ended their night at E11EVEN, not leaving until 5:30 a.m.

At the last club, they ran into Paris Hilton, and Cyrus was spotted making out with the hotel heiress, a spy at the club revealed to FOX411.

“The three left [together], helping each other out,” our source recalled.

The trio and scores of other stars are in town for Art Basel, an annual celebration that showcases art and performances.
