Not quite "Barack Osama" but come on people, get your facts right (via NYTimes):
A review of the concert film ''Fade to Black'' in Weekend yesterday misidentified a star appearing in the film with the rapper Jay-Z. She was Foxy Brown, not Lil' Kim. Because of an editing error, a picture caption misidentified the singer dressed all in white. He was R. Kelly, not Jay-Z.
