Jennifer Hudson channels her inner Mariah by acting a diva at Hammerstein Ballroom concert

Jennifer Hudson channels her inner Mariah by acting a diva at Hammerstein Ballroom concert: "Jennifer Hudson could be the next Mariah Carey — and not just because of her killer pipes and curves. The slimmed-down songbird showed off her diva-licious side at the second annual Mary J. Blige Honors Concert on Sunday, where a source at the Hammerstein Ballroom says Hudson kept media waiting on the red carpet while she did a sound check inside. When she finally left via the back door, she hopped in what our source says was a white Rolls-Royce to be driven 'around the block to the carpet.' There, 'her makeup artist and hair stylist hopped in the car to touch her up' before her closeup. Despite the high maintenance, our insider tells us Jen was 'very sweet' all night."
