Mischa Barton's ex Cisco Adler & Paris Hilton Make-out

Beauty Paris Hilton is being slammed for her man eating - drug using ways. The Simple Life star was out at Guy's nightclub in West Hollywood on July 24, Hilton and Mischa Barton's ex Cisco Adler sang karaoke, made out and got high.

The pair arrived at nearly 1 a.m. with two other girls. Hilton didn't get her own tail, but she stole sips from Adler's vodka tonics throughout the night. Later, Hilton sang "Bette Davis Eyes" in honor of a friend's birthday, and stayed onstage for an unexpected encore when the DJ started playing her single, "The Stars are Blind."

Usmagazine.com reports the duo made out more than once due to the marijuana they were openly smoking at the club
