Mariah Carey had a festive night on "American Idol" Wednesday. Not only judging the top 8 performers, giving energetic critiques and advice, Carey had fun with Smokey Robinson and her good friend, B. Scott.
"Such incredible songs tonight by some of the greatest songwriters in music..Stevie, Smokey, Holland-Dozier-Holland, I love it!!! #idol," she tweeted from the set.
Happy Birthday MC !
