Justin Bieber: It's 'Lame' That I Was Called a 'Brat'

Almost a year after Bieber, 17, filmed a guest spot on the hit CBS series, Helgenberger recalls the experience as less than pleasant.
"I probably shouldn't say this, but he was kind of a brat," the Emmy-winning actress, 52, said Friday in an interview with the French radio show Le Grand Direct des Medias.
Although Helgenberger admits the "Baby" singer was "nice" to her, she claims he "locked one of the producers in a closet and he put his fist through a cake that was on the craft services table."
The actress's comments did not go over well with the Biebs, who took to his Twitter account to call her out. "It's kinda lame when someone you met briefly and never worked with comments on you," the pop star wrote on Monday. "I will continue to wish them luck and be kind."
Calling Helgenberger's comments "rumors," Bieber added, "I know who i am and sometimes people r just going 2 say what they want. Keep ur head up and be the man ur mama raised. #killemwithkindness."
