Justin Bieber is a brat

Finally someone dishes the dirt on Justin Bieber, other than talking about his relationship with Selena Gomez, which everyone knew about months before they admitted it anyway. Actress Marg Helgenberger, who stars on CSI and recently worked with Bieber when he guest starred on the show, wasn’t terribly impressed with the pop star’s behavior, calling him a “brat” and claiming that he did quite a few unnecessarily immature things.

Apparently Bieber ruined a cake that was brought on the set by putting his fist through it as a “joke,” and then as another “joke” he decided to lock the producer of the show in a closet.  Charming.
