LIL’ Jon and Niki Taylor from “The Real Housewives of Atlanta” drew their respective teams extra support at yesterday’s taping of “Celebrity Apprentice.” Challengers had to sell Famiglia’s pizza to raise money for charity. The night before, Justin Beiber tweeted to his 5 million followers, “If u r in NYC 2morrow my dude @LilJon is selling pizza from 11am-3pm at Famiglia Pizzeria on 757 Broadway for charity!” Toward the end of the challenge, sources said Light Group owner Andrew Sasson, who just happened to be walking by, used his black AmEx card to pay $10,000 to support Taylor’s team, which was shooting in Times Square. Sasson’s rep had no comment.
