Brandi Glanville wants LeAnn Rimes to get some help.

Real Housewives of Beverly Hills' star Brandi Glanville wants LeAnn Rimes, the step mother to her children to seek help.

The thin RHOBH beauty believes the 'Can't Fight the Moonlight' singer - who was treated for anxiety last year in a rehab clinic - ''may be unstable'' and thinks she needs to undergo further treatment.

The 40-year-old reality TV star, who is promoting her memoir 'Drinking & Tweeting and other Brandi Blunders,' told Life & Style magazine: ''LeAnn needs to get help. She may be unstable, and I am concerned. I want to protect (my children). I want to make sure she's as healthy as she can be.

''There are clearly some issues going on, and I need to know my kids are okay when they're with (LeAnn)!''

A spokesperson for 30-year-old LeAnn - who is happily married to Brandi's ex-husband Eddie Cibrian - dismissed the reality star's latest attack and defended the singer, saying: ''This is a ploy to sell more books. If anyone needs help, it's Brandi. That should be obvious to anyone who's read her tweets.''

Brandi - who shares two sons, Mason, nine, and Jake, five, with Eddie - previously said she wanted to end her long running feud with LeAnn.

She said: ''I'm ready to put it behind me ... This [book] is my final chapter, this is me closing the door on our public fight. I want it out of the media, I'll just deal with it as best [as] I can with them.

''We don't have the best communication or relationship right now but, I'm hoping we can change that. I don't think we'll be friends, but I hope we can co-exist peacefully.

''I think once she has a child of her own, I think she will understand boundaries and what's respectful to do and how to handle things a little better.''
