Lisa Rinna embroiled in bitter feud!

Lisa Rinna hates Star Jones!

The pair apparently butted heads during Lisa’s stint on Celebrity Apprentice. Lisa was fired by Donald Trump on last night’s show.

“Since the show wrapped, there’s been no love lost between Star and Lisa,” a source told PopEater.

“Things got so ugly between them that NBC legal had to get involved.

“Lisa feels betrayed by Star and Dionne Warwick and has never in her life been exposed to such a negative environment.

“She comes from a place of love and refuses to fight dirty even if that means she would not win. To be honest, she’s happy it’s all over and has moved on.

“At least she left with her class and dignity in place.”

Meanwhile, Rinna isn’t replacing Regis Philbin on Live with Regis and Kelly despite rumors to the contrary.

Sources say Lisa wants to be considered for the gig, citing the success of all-female-anchored shows like Kathie Lee Gifford and Hoda Kotb on the fourth hour of Today.

But an ABC insider says it’s unlikely.

“We haven’t even started looking for a replacement, but Lisa is not on our radar,” the source told New York Post gossip column Page Six.
