The NY Post is reporting that Jermaine Dupri enjoyed a bit too much of Jay-Z's Ace of Spades Champagne and Petro tequila the other night at his birthday party at Tejune in NYC ...

They say he threw up all over girlfriend Janet's lap, sending her rushing for cover in their chauffeured car outside the club!

True? Not sure, but it totally reminded me of this fateful night when Brit vomited all over her then-boyfriend Isaac Cohen ... remember this? ...
