Miley Cyrus gets wild with her friend Jaci Wells at Wayne Coyne's art gallery bash Credit: Jaci Wells

Leave it to Miley Cyrus to incorporate marijuana leaf pasties into her holiday party ensemble. The “Wrecking Ball” singer bared her breasts and locked lips with her new female friend Jaci Wells in a series of photos taken at Flaming Lips frontman Wayne Coyne’s art gallery bash at The Womb in Oklahoma City home on Saturday, Dec. 20.

After venturing around what looked like the Grand Canyon in Arizona — and wearing equally insane outfits — Cyrus, 22, landed at her pal’s art gallery for a seemingly wild night. In one photo, the singer, dressed as an elf, locks lips with her friend Jaci Wells while a Santa-clad arm touches her exposed breast. "She's a ton of fun and super down to earth. It was really comfortable being around her,” Wells tells Us Weekly of meeting the star. “[It was] definitely [my idea to kiss Miley]. You can’t meet Miley and resist the urge to kiss her,” she added.

In another equally risqué snap, Patrick Schwarzenegger’s girlfriend shows off her breasts, barely concealed by pasties. “I had ‘Free the Nipple’ [written] on my chest and Miley said, ‘My boobs are out,’ so that’s [how that picture] happened,” Wells explained. 

Confusingly, Cyrus completed her wild look with a purse which read “I have no tits.” In an Instagram posted by the songstress, the overall tone of the night could be explained by a snap of an unidentified male dressed as Santa getting a tattoo.

Getting close with girlfriends is nothing new to Cyrus. Earlier this month, sources tell Us the former Hannah Montana star locked lips with Paris Hilton in front of Schwarzenegger at a club in Miami.

Liam Hemsworth’s ex gave her beau a shout-out on Instagram while on her psychedelic-looking vacay, writing on an Instagram of his socks, “Ohhhhhh iiiiii wishhhhhhhhh youuuu wereeeee hurrrrrrr.”
