Brandi Glanville: Run-in with LeAnn Rimes "Not Pleasant"

In the midst of her divorce from actor Eddie Cibrian, model Brandi Glanville is speaking out yet again against her rival, country star LeAnn Rimes.

In Las Vegas Saturday night, Glanville, 36, acknowledged that she has had a run-in with Cibrian's current girlfriend, and that it was "not pleasant.”

LeAnn Rimes and Eddie Cibrian took their romance public in August and have been staying at a house near the home she used to share with Cibrian.

Still, the estranged couple "definitely save face for the kids – absolutely, they are the most important things in both our lives," Glanville said.

That's good to hear at least. In fact, Cibrian was watching the kids - Mason, 6, and Jake, 2 - during Glanville's weekend away in Sin City.

Rumors of Eddie Cibrian cheating on Brandi Glanville first surfaced this spring.

Glanville said she was in Las Vegas with girlfriends for a "divorce celebration-slash-get-away-from-your-life party. I'm just here to enjoy myself and relax."

A divorce party? Shanna Moakler would be so proud.

Brandi left Eddie over the affair with LeAnn in July.

As for Rimes, who filed for divorce from Dean Sheremet September 1, "she can have most of everything," said Glanville, "just not my children and my family."

A friend of Rimes says, "This is absurd. It just sounds like someone's desperately trying to extend their 15 minutes here. Everyone else has moved on."
