Justin Bieber Discusses Career Backup Plan On 'Tonight Show'

'I always wanted to be a car mechanic,' Bieber tells Jay Leno.

Sure, things are going well for [artist id="3187077"]Justin Bieber[/artist] these days. He's got the #1 album in the country and 1.7 million Twitter followers (and counting), and he pulled off Thursday's best April Fools' prank when he seized control of Funny or Die, renaming it Bieber or Die. But if this whole teen sensation shebang doesn't work out, Bieber has a backup plan that involves the career he had a hankering for before music swept him up.

"I always wanted to be a car mechanic," the 16-year-old told Jay Leno on Thursday's edition of "The Tonight Show."

And now Biebs can actually drive a car, having hit the legal driving age last month. "I got a Range Rover," he said. "It's my first car. I don't want to get too flashy."

Before sitting down to chat with Leno, the singer busted into a rendition of his hit single "Baby," the same tune he performed last week on "The Late Show With David Letterman." Earlier in the evening, he appeared on "Chelsea Lately," where he did not sing but instead confessed he'd like to date either host Chelsea Handler or Kim Kardashian. Yes, it's been a busy couple of weeks for Bieber as he promotes his new album, My World 2.0, and gets set to launch an international tour in June.

So how did this all happen for him? How did Bieber end up a pop star and not a mechanic? On "Tonight," the singer told an amusing version of how he was discovered after posting videos of himself on YouTube.

"I started posting videos online and I just started getting bigger and bigger," he laughed. "I got found by this manager who introduced me to Justin Timberlake and Usher, who both wanted to sign me. So we ended up in that war. Actually what happened was we went to Vegas. It was Usher and Justin — they got in the ring. Justin lost. He got knocked out."
