Austin Mahone: 'I punched someone for talking about my girlfriend'

Heartthrob Austin Mahone recently confessed a dark secret about his past and revealed that he once punched someone for bad-mouthing a girl he dated.

Speaking to MTV News, the singer explained that he heard another guy talking about his girlfriend and didn't like it, so smacked him: "This kid was talking about my girlfriend, so I punched him. But, it worked out, because it was right before Christmas break, so I got three days extra."

Mahone also opened up about his first kiss and admitted that it was a little unusual, happening when he was "13 and under water". He then said that his celebrity crush is Rihanna "because she's hot".

The star recently sat down for an interview with Chelsea Handler and shared details of his first ever job, which he didn't enjoy: "I had a job setting up bowling pins. They would make kids go and set up the pins after they got knocked down. It was child slavery... It was horrible."
