Lindsay Lohan is rippin' a move straight from the Anne Heche sexuality playbook -- last night the part-time lady lover was making out with a dude!
Lohan -- who recently broke up with Sam Ronson -- went full tongue-to-mouth with the mystery man at a place called Church Boutique on Santa Monica Blvd.
Not everything's changed though -- after the makeout session ... the next thing LiLo put in her mouth was a cigarette and swig of Red Bull.
UPDATE: The makeout buddy is apparently a 29-year-old French actor named Aurelien Wiik.
