Selena Gomez better hide her Uggs if she's got any -- because they're a big turn-off for Justin Bieber.
The 16-year-old megastar opens up about his dating habits in the special edition Us Magazine bookazine called "Justin Bieber: My Private World" -- telling the mag he's looking for "“A funny, brunette girl who can have civil conversations. But no Uggs. They're ugly!"
With an exhausting touring schedule, the Biebs says he always makes it "a priority" to find time to date ... adding, "but it's hard with my mom always around."
Though he's currently linked to Gomez, Justin also says he'd be open to dating a fan "as long as they aren't crazy!"
The bookazine, featuring photos, interviews and six fold-out posters, drops tomorrow.
