Now Justin Bieber has his say over Mariah Carey

Justin Bieber arrives at the Late Show with David Letterman in NYC, signing autographs for fans - including one man's palm!

Don’t mistake the little singer for a quite mouse, he’s now had his say over Mariah Carey’s career!

After we reported the other day that Ke$ha had made comments about Justin Beiber not being fit, he’s now spoken out about Mariah Carey. He told The Sun that he preferred the warbler’s older material. 82nd Annual Academy Awards - Arrivals

Bieber said, “I don’t love her new music, it’s not the same. It’s like Michael Jordan coming back out to play in the NBA. She is past her best.”

Ooo ouch! This comment comes as it’s announced that Mariah’s 13th album that was supposed to be out in the UK in April, has been cancelled. Is it all over for her?!
