Justin Bieber makes a joke about underage girls before backtracking

Justin Bieber took things too far after he made a joke about underage girls.

During a concert in Toronto, the 21-year-old singer asked about the ages of his fans at an acoustic concert on Monday.

"Who's 13 in here? We got any 13 year olds?" he said, drawing big cheers from the crowd at the Danforth Music Hall. "We got any 14 year olds?"

He continued, "So, uh, 14," and then began counting his fingers.

"Four more years until you're 18," he said over the microphone.

Justin laughed as the crowd continued applauding him, but he quickly corrected himself.

"Too much, Justin," he said.
