Music Mogul Sean Combs and rapper Lil Kim participated in a Timbaland concert at Irving Plaza in NYC last night. I didn’t know Timbaland could sing? Anyway, staying true to his narcissistic form, Sean is planning to throw an extravagant, over-the-top ‘King of New York’ themed 16th birthday bash for his oldest son Justin, who just turned 16 two weeks ago.

Sean is inviting the world’s most conceited artists, Jay Z, Beyonce and Chris Brown to join Snoop Dogg, Lil Kim and others in celebrating the birthday of his already over-indulged son who has a restaurant named after him. Of course, the entire self-serving affair will be filmed for MTV’s egocentric “Super Sweet 16” show. A source tells the NY Post that a NYC club will be decorated with images of NY’s skyline. Oh, and in lieu of birthday gifts, Diddy is asking his well-heeled friends to donate to the Haiti relief fund. But before you think Sean is teaching the youngster the importance of generosity by foregoing gifts in lieu of charity, friends tell me that Justin already received his presents on his actual birthday, including his biggest gift — a car.

Few of us can forget young Justin’s last extravagant birthday bash where he was treated to a lap dance by a fast teenager.
