(CBS) Justin Bieber is firing back at "CSI" actress Marg Helgenberger, who called the pop star a "brat" after the two worked together last year.
The 17-year-old singer tweeted, "It's kinda lame when someone you met briefly and never worked with comments on you. I will continue to wish them luck and be kind."
"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," he added in another post, followed by, "Rumors are just that...rumors. In the end if you just be kind and be yourself people will know who you are. That goes for anyone i think."
Helgenberger's comment came during an interview with French magazine Le Grand Direct des Medias, in which she said of Bieber, "I shouldn't be saying this but he was kind of a brat [on the set]."
"He was very nice to me," she continued, "but he locked one of the producers in a closet" and also "put his fist through a cake" that was on the craft service table.
Bieber made his acting debut last year on the CBS drama, when he appeared in two episodes.
