Not even Justin Bieber could let himself get away with this one...

The 21-year-old singer immediately called himself out for a pretty creepy joke he made to some of his teenage fans during a Monday night concert in Toronto.

"We got any 14-year-olds?" Justin asked, before counting from 14 to 18 on his fingers. "We got four more years, and then you're 18."

"Too much, Justin," he immediately followed up his remark.

Meanwhile, Justin is expanding his body art collection! On Thursday, the "Sorry" singer debuted a brand new neck tattoo of a pair of wings (it appears to be the same wing design Justin used on his "Believe" tour), writing, "New tattoo :)."

Looks like Justin got his wings.
