Do not mess with Babs! 

Jill Zarin is used to cat fights, but not one this epic.  The former The Real Housewives of New York City star attended a private event in Los Angeles where Barbra Streisand performed, and Zarin posted a video of Babs' performance on Youtube.

As fast as you can say Oscar-winner, Barbra’s high powered attorneys reached out to Jill and demanded that she take down the video immediately.

Jill informed her fans on Twitter of the brewing legal trouble.

“Someone from Barbra streisands company just called my store to tell me to take down my YouTube video or they will sue me. Is that nuts? Sorry guys. I took it down!” she wrote.

That is one person in Hollywood you do not want to be sued by!
