He looks hot from behind --so who's that celeb smoocher?
It's none other than nortorious womanizer Collin Farrell and his new lady love, Mexican-born Polish actress/singer, Alicja Bachleda Curus. The couple -- who met on the set of the movie Ondine --couldn't keep their hands off each other as they checked into the Bel Air hotel in Los Angeles on Tuesday, which happened to be her 26th birthday. They're actually both "May babies". Farrell turns 33 on May 31.
Curus -- who's appeared in several German and Polish films and television shows -- won rave reviews for her devastating and powerful portrayal of a woman kidnapped and about to be sold into sexual slavery in the 2007 film Trade.
