Justin Bieber Was "A Brat" On CSI Set
His co-star Mary Helgenberger has revealed she's not JB's No.1 fan...
Justin Bieberhas been branded "a brat" by his CSI co-star, Mary Helgenberger.
Helgenberger, who plays Catherine Willows in the US crime series, slammed the Biebster's behaviour during his guest slots on the show, stating to a French radio station that she wasn't impressed with JB's attitude on set.
According to TMZ, when the actress was asked about the Baby singer's involvement on CSI, Mary replied: "Justin Bieber wasn't bad. He had never acted before."
The radio station continued to probe Mary over her thoughts towards Bieber, leaving her to admit that during his time on set, he acted childishly.
Speaking of the 17-year old - who played troubled teen Jason McCann in the series - Helgenberger confessed: "I shouldn't be saying this, but he was kind of a brat [on the set],"
She explained: "He was very nice to me, but he locked one of the producers in a closet, and he put his fist through a cake that was on the actors' table."
It seems Helgenberger hasn't been struck with Bieber Fever just yet!
In other JB news, the teen heartthrob has quashed reports that he would be cancelling the Japan leg of his tour, confirming the shows will still be going ahead.
As we previously reported, members of Bieber's crew had allegedly refused to go to the country, fearing for their health after the recent earthquake in Japan.
Justin took to Twitter to announce he will be bringing his My World tour to the nation, stating: "5 shows left of this leg of the My World tour! Manila, Hong Kong, Taipei, Osaka and Tokyo! Like I said... we are going to Japan!"
He will now play two live dates in Japan on 17th and 19th of May.
