JMac's 'Leavin' His Underage Drinking Years Behind As He Turns 21

I know I'm an hour late since it's 1 in the morning on April 10th right now, but I still must congratulate fellow Westchesterian Jesse McCartney on turning 21 on April 9th. I hope he didn't party too hard last night. Last week TMZ reported that JMac's neighbors were told to call 911 if his 2:30 am parties got out of control. Guess he should have stayed in NYC. New Yorkers have the right idea: crash the party, don't let the cops shut it down.

Check out Jesse's new vid for Leavin that shows off his "grown-up 21 year old" side:
