Dupri vomits on Janet at birthday event?

Jermaine Dupri was sick on Janet Jackson at his 36th birthday party, say reports.

The music producer "vomited in Janet's lap", according to the New York Post.

Jackson allegedly "bolted out of the scene" afterwards.

Earlier in the evening, the pair shared bottles of tequila and Jay-Z's Ace Of Spades champagne at the Tenjune venue. Guests included Ne-Yo, Busta Rhymes and Ice-T.

Representatives for the couple have not commented on the incident.
