Brandi Glanville has confessed she used to keep her ex-husband Eddie Cibrian happy in the bedroom by having the ''occasional lesbian make-out''.
The 'Real Housewives of Beverly Hills' star has revealed she would indulge in the ''occasional lesbian make-out'' to impress her ex-husband and believes their steamy sex life was the main reason their marriage worked.
In her new tell-all memoir, 'Drinking & Tweeting and other Brandi Blunders', Brandi writes: ''I can definitely appreciate a pretty girl, so on occasion I would hook up with girlfriends, so that my husband could watch. (Sometimes the girl had a boyfriend and husband, too, who also seemed to enjoy the show.)
''It was harmless and Eddie seemed to appreciate it, because without fail, it would lead to some pretty hot sex afterward. Like I said, I was just an average Hollywood housewife doing whatever I could to keep my husband happy.''
Brandi - who admits she still loves Eddie - doesn't understand how the father of her two children found the ''extra energy'' to cheat on her in 2009 with his now wife, Leann Rimes, because she thought they had a very fulfilling and loving marriage.
She ranted: ''Let's be clear. Eddie and I had an extremely healthy sex life (so where he got all that extra energy, I'll never be sure), but every so often we would run away together so we could make love in the middle of the afternoon. And he would kiss me the way he did when we had nothing but time.''
These saucy revelations come after the 40-year-old reality star admitted she used Eddie's credit card to splash out $12,000 on a vaginal rejuvenation procedure as revenge for him cheating on her.
Her long-time rival LeAnn, who wed Eddie in 2011 after legally separating from her husband Dean Sheremet, is said to be ''shocked'' and in a ''fragile state'' after reading the advance excerpts of Brandi's book.
