Brandi Glanville has branded Leann Rimes ''insane''.

The 'Real Housewives of Beverley Hills' star has once again lashed out at her ex-husband Eddie Cibrian's wife LeAnn, claiming her emotional outbursts about her stint in rehab and her fear of losing Eddie prove she is mentally unstable.

Speaking on 'Watch What Happens Live' on Monday night (21.01.13), Brandi sighed: ''Everyday there's a tell-all. It's kind of cray-cray!''

Asked if she thought the 'Can't Fight The Moonlight' country singer was legitimately crazy, she quipped: ''Insane? Yes I do!''

The sharp-tongued blonde went on to slam Eddie - who began a relationship with LeAnn while he was still married to Brandi and LeAnn was wed to Dean Sheremet.

Brandi insists Eddie - the father of her children, Mason, nine, and five-year-old Jake - is repulsive to her now.

She exclaimed: ''I just would say no. He, at this point ... I care about him as the father of my children ... [but] even if we're in the same room, he makes my skin crawl!

''I've lost respect for him and when you lose respect for someone, you can't go back. I always go for the hottest guy in the room - and he's that guy - but there's zero attraction.''

However, she couldn't dismiss his skills in the bedroom and decided to be honest when asked to rate him out of 10 as a lover.

She said: ''I would say he's a nine. I was with him for 13 years. I wouldn't stay if it wasn't, like, a total package.''

Brandi and LeAnn have been locked in a bitter feud for months and while LeAnn recently announced she wanted to end the war, the 30-year-old star was quick to retaliate on Twitter during the broadcast of Brandi's outspoken interview.

LeAnn scoffed, ''Wow the texts from my friend. KISSES and KMA'', meaning ''Kiss My A**''.
