Don’t look Justin Bieber — your girlfriend is kissing another man!
Luckily for Selena, her and Nat were just acting out a scene for their new movie Parental Guidance!
Selena, 20, and Nat, 17, enjoyed one of the many perks of acting as they passionately held one another during the tender lip lock.
Selena’s new film is an adaptation of Ric Browde’s 2000 novel While I’m Dead … Feed the Dog.
Justin, 18, has visited the set before, but we’re not sure he would have enjoyed this day full of kisses!
What do YOU think of Selena’s hot lip lock,
