Blue singer LeAnn Rimes is accused of cheating on her husband after she was allegedly caught on camera kissing another man.

Leann, who has been married to back-up dancer Dean Sheremet (pictured above) for seven years, is reportedly having an affair with actor Eddie Cibrian, her co-star in the upcoming TV movie Northern Lights.

According to a scoop featured in this week’s edition of UsWeekly, security camera footage from the Mosun and Club M in Laguna Beach, California caught the country star sharing a smooch with Eddie over dinner earlier this month.

Say it ain’t so, LeAnn!

Northern Lights, a Lifetime original movie based on the best-selling novel by Nora Roberts, will debut on March 21. The movie also stars Patricia Arquette.
