The Biebs has turned over a new leaf!

Justin Bieber taped his Comedy Central roast over the weekend, and there was no shortage of jabs he had to endure from the celebrity guests. The singer did, however, use the occasion as a way to apologize for all his past bratty behavior, including drag racing and egging his neighbor's house. "I just want to be able to laugh at myself," he told Today before the show.

JB might be new and improved, but he's still got a little of his bad boy swagger. When asked what he planned on doing after the roast, he gave a pretty typical reply for a young rich heartthrob.

"Im going to Vegas... on my jet, b**ch," he told reporters.

Some things never change!
