Pop star Britney Spears reportedly screamed at a 13-year-old kid who had been in a fight with her little sister, leaving the traumatised child in tears

Britney stormed the set of her little sister Jamie Lynn Spears Nickelodeon show, Zoey 101, last week and let the talent coordinator bring [co-star] Alexa Nikolas over to Jamie Lynn trailer.

There she proceeded to scream that Alexa was an evil little girl, and that she had better watch herself or she will never work in this town again! a source was quoted as saying.

Alexa was in tears. She was sobbing and totally upset - I mean, she has been buying Britney CDs since she was 6, and then Britney tears her to pieces? It was totally uncalled for. While Jamie Lynn is the star, Alexa still works there and it is technically her set. And the fight was a petty, 13-year-old thing between Alexa and Jamie Lynn, who is becoming a real pest. Britney should have stayed out of it, he added.

But a spokeswoman for both the Spears sisters has a different story to tell “Jamie Lynn and another girl on set were having problems, as 13-year-olds do. Britney did have words with the girl, but felt she was sticking up for her sister. She did not yell by any means, she just gave the girl a sisterly talking to and wondered why they just couldn’t all get along�
