Fashion Police co-host Giuliana Rancic made some threats against a certain reality star during her Tuesday appearance on Watch What Happens Live.

Host Andy Cohen asked Rancic, who was on the show with her husband Bill Rancic, whether she had chosen sides in the feud Brandi Glanville is allegedly in with LeAnn Rimes.

Yes!" the 38-year-old said, before explaining why she supports Rimes. "Even before I really knew LeAnn, I interviewed LeAnn. I think there's more to the Eddie/Brandi story than maybe we all know. So I don't think we should be so quick to judge that whole situation."

The Giuliana & Bill star said tension heightened between her and Glanville after Giuliana made a comment on Fashion Police that was in support of Rimes. Giuliana said in a May episode that Rimes and Cibrian are "soul mates" and that the Housewives of Beverly Hills star is "nuts."

"[After that, Brandi] went out and tweeted something, and she said, 'How would you like if your husband left you behind - you and your surrogate baby,'" Giuliana said.

She and Bill welcomed their son Edward in August 2012 via gestational carrier.

"Here's the thing: say what you want to me- don't ever bring my baby into that, ever," she told Cohen. "I love Beverly Hills, and I love all the housewives, but I will cut Brandi if she talks about my baby again."

Glanville has not commented on the statements made by Giuliana.

Rimes is married to Glanville's ex-husband, Eddie Cibrian. The couple met on the set of their Lifetime TV movie Northern Lights and had an extra-marital affair while Cibrian was still married to Glanville and Rimes to Dean Sheremet.
