Eddie Cibrian's estranged wife has confirmed she is filing for divorce, amid allegations the actor is having an affair with his NORTHERN LIGHTS co-star Leann Rimes.
Rimes and Cibrian have been dogged by romance rumours since they were caught on camera kissing during an intimate dinner in California in March (09) while on a break from filming the TV movie.
The Blue singer is rumoured to have split from her husband of seven years Dean Sheremet, while Cibrian - who has denied an affair - has separated from his wife, Brandi Glanville.
The pair stepped out together to attend a Kings of Leon concert in Los Angeles at the weekend (22-23Aug09) just days after Cibrian was snapped leaving Rimes' home in Santa Monica, California after allegedly spending the night.
And Glanville admits her estranged husband's recent outings with Rimes have prompted her to make their split official.
She tells People.com, "I don't understand. You think you know one thing and you wake up and it's all been a lie. He's just somebody I don't know... I'm just like, 'You know what? You're not the man I married.' There is one side of him that I absolutely love and always will, but that side of him is not the side I'm divorcing."
Cibrian and Glanville share sons Mason, six, and Jake, two.
Spokespersons for Cibrian and Rimes had not responded to requests for comment as WENN went to press.
