Singer Leann Rimes is embroiled in claims she is cheating on her husband after she was allegedly caught on camera enjoying a steamy date with a co-star.

The Blue hit-maker, who has been married to back-up dancer Dean Sheremet for seven years, is reportedly having an affair with her TV movie Northern Lights co-star Eddie Cibrian, according to UsWeekly.

The publication claims that shocking security camera footage caught the clean-cut country star kissing the actor on an intimate date at Mosun and Club M in Laguna Beach, California earlier this month.

And it seems the pair hit it off immediately on-set - their Northern Lights director Mike Robe had previously told UsWeekly.com, "From the moment we rehearsed, LeAnn and Eddie honestly developed a really strong bond and a warm relationship."

The singer renewed her wedding vows to Sheremet last August. Cibrian has been married to model Brandi Glanville since 2001, and has two young sons. A representative for Rimes tells the publication, "We do not comment on our clients' personal lives."
