Us Weekly reports:

Britney Spears' cousin and former assistant Alli Sims was not involved with rescuing the singer during her breakdown last night.

PageSix.com reported Sims used "brute force to pry the singer out of the bathroom where she had barricaded herself with son Jayden James late last night."

But Sims tells Usmagazine.com: "I absolutely was not there. And even if I was there I would not have banged down the door with a hammer, that's not my style. I would have knocked!"
