ABC Family’s “Pretty Little Liars” boys, Ian Harding, Drew Van Acker and Tyler Blackburn, set the red carpet on fire with their presence at the 102.7 KISS FM’s Jingle Ball held at Nokia Theatre LA Live in Los Angeles, California on Saturday (December 3)- more pictures below.

When asked if and why didn’t they hook up with their equally hot co-stars, Lucy Hale and Ashley Benson, the men of Rosewood claimed they are all very professional on set. It’s supposed to be a family show, so the hotties cannot just admit they are having wild make out sessions on set… between takes… while the cameras are off! Right?

Ian Harding, best known for playing high school teacher Ezra Fitz who maintains a forbidden relationship with one of his students, admitted he was excited to see Lady GaGa perform, speculating she would be wearing “something that was alive at one point, like earlier today alive.”

The second half of Pretty Little Liars season 2 returns to ABC Family at 8/7c on Monday, January 2, 2012.
