Ohh la la, little miss Miley Cyrus and heiress Paris Hilton reportedly got hot and heavy this weekend, locking lips at a Miami nightclub.

Cyrus and her boyfriend Patrick Schwarzenegger were in south Florida on Friday night for the Art Basel Miami party. Miley and her man were reportedly seen at a number of different clubs before winding up super late night at E11EVEN, the cabaret/nightclub in South Beach where the kiss took place, E! News reports.

Before leaving E11EVEN at around 5:30 a.m., Cyrus went all bi-curious, engaging in a mega make-out session with Hilton in front of a teeming dance floor filled with other partygoers. Schwarzenegger reportedly stood idly by, not having been invited to turn the make-out into a ménage.

Before hooking up with Hilton, Cyrus and her beau kicked off the evening's festivities at the Moschino Barbie party. The party was thrown to honor "creative director" Jeremy Scott's self-titled first book debut.

Later in the night the pair were seen partying at a club called Shore, where they were invited to join DJ Paul Oakenfold and David Arquette in the DJ booth. The two lovebirds also reportedly made rounds at the 10AK and Up & Down pop-up at Rec Room. They finally ended the night on a high note at E11EVEN where the girl-on-girl action went down.

HollywoodLife.com reports that Cyrus' recent increasingly wild antics over the past weeks and months -- including being seen topless out on the town and twerking on strippers -- have been some sort of retort made toward the refusal of her boyfriend's mother to accept their relationship.

Most recently, Schwarzenegger's mom Maria Shriver (yes, that Maria Shriver) allegedly forced her son to un-invite Cyrus to a Thanksgiving dinner party that she threw because she didn't want the starlet there. Shriver has reportedly been dead set against her son and Cyrus' relationship since its inception.

Will Mama Shriver and Miley ever made amends? And if not, what kind of effect will their inability to get along have on Cyrus' relationship with Schwarzenegger? We will definitely keep watch and be sure to let you readers know how things evolve. Stay tuned!
