While Justin Bieber got slammed for leaving an arrogant comment on the guestbook at the Anne Frank House in Amsterdam a few days ago, 50 Cent didn't think the 19-year-old singer did anything wrong. "She probably would have been [a belieber]," 50 Cent told Vulture at the premiere of new movie "Pain and Gain" on Tuesday, April 16.

Not only did he defend Bieber, but 50 Cent also supported the pop star's career. He believed that Bieber was talented that he could reach the potential of the late Michael Jackson. He continued, "He can be one of those guys who can eventually transition like that."

Mark Wahlberg, who was present at the same premiere, also sided with the ex-boyfriend of Selena Gomez. Wahlberg told the magazine, "I think it's best to put down the phone and Twitter and all that stuff, and just be a little more low-key right now. Because they're watching every move he makes, everything he says, and less is more. Go take a vacation."

Even Anne Frank's stepsister, Eva Schloss, thought that the Canadian star's comment wasn't a big deal. She told The Telegraph, "She probably would have been a fan. Why not? He's a young man and she was a young girl, and she liked film stars and music. They make a lot of fuss about everything that is connected with Anne Frank."

Previously, Bieber caused a stir after visiting Anne Frank museum in Amsterdam on Friday, April 12. He left a note on the guestbook, which read, "Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a belieber."
