Csi: Crime Scene Investigation star Marg Helgenberger regrets branding Justin Bieber "kind of a brat" after his stint on the show, insisting her comments were made during a "silly" interview.
The Baby hitmaker signed on to star in the TV drama as troubled teen Jason MCCann last year (10), and was asked back for a second episode earlier this year (11).
Helgenberger shot one scene with the teen idol, but she was unimpressed with his behaviour, telling a French radio show, "He never acted before. I mean, I shouldn't be saying this but he was kind of a brat. He locked one of the producers in the closet, (and) he put his fist through a cake that was on the cafeteria table."
But the actress admits her remarks were inappropriate and she regrets speaking out about Bieber's on-set antics.
She tells Bbc's Newsbeat, "Justin - there was one little scene in which we were together. Actually, he was really sweet to me.
"Comments I made at one point, I regret saying them - not that they weren't true, I said it as part of the interview, being sort of silly. I think he's a very talented kid."
