Jermaine Dupri: Celebrating New Baby?

UPDATE: New photos from inside the event have been added, featuring Kim Kardashian and her sister Khloe, from their video game launch to Kanye’s table. To check out even more pics and a behind-the-scenes account, visit Khloe Kardashian’s official Web site.

If Janet Jackson is indeed pregnant, her partner in crime Jermaine Dupri is already passing around the cigars.

Celebuzz sources spotted the power producer Tuesday night at West Hollywood’s Apple Lounge, sitting deep in VIP territory alongside Kanye West.

“Jermaine was really holding court,” the source said. “Champagne was everywhere.”

Celebrating anything, JD?

His table included a casual West (who we’re told chatted up two young blondes), Kim Kardashian and Gnarls Barkley star Cee-Lo.

Jackson, 42, has been dating 36-year-old music man Dupri for six years.

Though Jermaine recently told Us Weekly that Jackson, in fact, is not with child, Life & Style weekly was confident enough to announce she is carrying a baby on this week’s cover.

Her dream’s finally coming true, but Janet’s scared about becoming a mom at 42,” the cover screams.

Reps for Jackson and Dupri have been contacted for comment.
