Barf!

Jermaine Dupri is getting a little too old to pAArty hard these days!

To celebrate his 36th birthday, the music man went with longtime girlfriend Janet Jackson to club Tenjune in New York last week.

The two shared bottles of Patron tequila and champagne with party guests like Ice-T, Busta Rhymes, and Ne-Yo.

Lots of fun was had by all. That is, until Dupri reportedly vomited… on Janet’s lap!!!!

EWWWWW!

A source says, “Ms. Jackson bolted out of the scene and sped off in her chauffeured Maybach.”

Jackson and Dupri’s reps have not returned any calls.

A rep for Tejune declined to comment.

And as for Dupri’s work life, sources are saying it’s not going so well.

An insider says about Janet’s album that the head of Island Def Jam, “L.A. Reid had wanted to make changes to the album, make it fresher with some newer artists added in, but Janet said no – and Jermaine backed her up. He looks silly right now.”

Poor Dupri!
