In the midst of her divorce from actor Eddie Cibrian, Brandi Glanville is taking the opportunity to speak out against her rival, country singer LeAnn Rimes
At the TAO/LAVO anniversary party in Las Vegas Saturday night, Glanville, 36, acknowledged that she has had a neighborhood run-in with Cibrian's current girlfriend that was "not pleasant.”
Rimes, 27, and Cibrian, 36, took their romance public in August and have recently been staying at a house near the home Glanville used to share with Cibrian.
Still, the estranged couple – who are parents to sons Mason, 6, and Jake, 2 – "definitely save face for the kids – absolutely, they are the most important things in both our lives," Glanville said. In fact, Cibrian was watching the kids during Glanville's weekend in Sin City.
Glanville added that 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."
As for Rimes, who filed for divorce from Dean Sheremet on Sept. 1, "she can have most of everything," said Glanville, "just not my children and my family."
A friend of Rimes says of Glanville's comments, "This is absurd. It just sounds like someone's desperately trying to extend their 15 min here. Everyone else has moved on."
