Brandi Glanville says her estranged husband's girlfriend LeAnn Rimes is a little too close for comfort.
"I have a new neighbor and her name is LeAnn Rimes. She's moved in a half a mile from my house and a block from my son's school. So she is completely space invading me at the moment so things are not cool," Glanville, 36, told Usmagazine.com at the anniversary celebration of TAO/LAVO in Las Vegas Saturday night.
Us Weekly first reported Eddie Cibrian, 36, was having an affair with Rimes, 27, his Lifetime movie costar. Cibrian filed for divorce in August, the same month Rimes and husband Dean Sheremet announced their separation.
Glanville says her run-ins with Rimes in Calabasas, Calif. are "not pleasant."
"There is a point where she needs to have a sensitive side and back the F up," she says.
Glanville says she even spotted Rimes in front of her six-year-old son Mason's school as she picked him up.
"Honestly, she's Single White Female-ing me. She wants my life," Glanville goes on. "She wants my kids. She wants my husband. She can have most of everything but just not my children or my family."
Glanville — who is also mom to two-year-old son Jake with Cibrian — says her kids "have no idea" that her parents are feuding. The kids are "used to daddy being gone for work, so it's not a huge transition," she explains.
Despite no hope of an amicable divorce, as she says, she tries to maintain the peace with Cibrian in front of their children.
"We definitely save face to the kids, absolutely," she says. "They're the most important thing in both of our lives."
