Sean “Diddy” Combs is throwing a star-studded “Prince of New York” 16th birthday party for his eldest son, Justin. The rapper — still on a high after his epic, “party of the year” 40th birthday bash in November — has lined up a series of big-name performers and guests including Chris Brown for the event at an unidentified local club on Saturday, which will be filmed for MTV’s “My Super Sweet 16.” A source said, “The club will be decorated with images from the New York skyline. Diddy will perform with his band, Diddy-Dirty Money, but there will also be some big-name performers taking the stage to surprise Justin.” Guests will also include Combs’ pals Snoop Dogg, Lil’ Kim, boxer Floyd Mayweather and possibly Jay-Z and Beyoncé. The source added, “It’s going to be big, but it won’t be as lavish as Diddy’s 40th. Instead of gifts, guests will be asked to make a donation to the Haiti fund.”
