The 30-year-old country singer has hit back at her husband Eddie Cibrian's ex-wife Brandi - who branded LeAnn ''insane'' and desperate in an interview on Monday night (01.21.13) - and claims she is fed up of her constant lying and negative comments.
Speaking to chat show host Jimmel Kimmel, LeAnn sighed: ''I usually don't engage. But there comes a time when you're just like, 'Screw you'. That's it, and that's all you wanna say and you're like, 'I'm done with this now,' for like another three months.
''I think it's kind of interesting how it seems one-sided most of the time. But then, you know, you just kinda get fed up with people lying about you and you're like ... words, here.''
The 'Can't Fight The Moonlight' singer and the 'Real Housewives of Beverley Hills' star have been engaged in a vicious mud-slinging contest for months. Brandi claims LeAnn - who hooked up with Eddie while they were both still married to other people - is a bad stepmother to her children, Mason, nine, and five-year-old Jake, while LeAnn regularly insists she wants to end the feud.
One thing troubled star LeAnn agreed with Brandi about, however, was that she is ''insane''.
She shocked the audience by telling TV host Jimmy: ''I am, though''.
LeAnn checked into rehab to undergo treatment for anxiety and stress last year, which she says was partly brought on by online criticism of her marriage to Eddie.
