Selena Gomez was probably not a fan of the fake mustache Justin wore to the MTV Movie Awards. (Getty Images) Kissy pictures or not, Selena Gomez still hasn't officially confirmed that she's dating Justin Bieber, but she does admit that she likes the "Baby" singer baby-faced.

While appearing on the Sirius XM radio show The Morning Mash, Selena was asked whether she minds it when Justin lets his facial fuzz grow. "I actually don't," she answered. "You've got to commit [to growing a mustache]. You can't just be like, 'Let me do a little one.'"

And for the record, soul patches don't do it for Selena either. "I don't like that," she offered of the devilish patches of hair under the lower lip. Earlier this week, Selena told David Letterman that she met Justin through her mom.

"His manager called my mom, who's my manager," she explained. But Selena cut off the talk show host before she revealed too much. "I'm blushing! He's been in my life for so long and it's just nice to have someone that understands what you're going through."
