Selena smooched another boy!

This one's true, but it's not what you think! When cameras caught Selena Gomez kissing actor Nat Wolff in Sherman Oaks, California, this August, Hollywood gossipers freaked out. Tiger Beat knows Sel was just acting in a scene for a new movie called Parental Guidance Suggested. In the movie, Selena plays Nina, and Nat plays Nina's crush, Ric. Our insider sources tell us Selena's boyfriend, Justin Bieber, visited her on set the day of her big smooch, and the superstar couple looked totally in love. Selena's such a professional that kissing another guy for a movie is no big deal! Parental Guidance Suggested is expected to come out in 2013.
