Seems that the sparks flying between LeAnn Rimes and co-star Eddie Cibrian weren’t only on screen.  According to Us magazine the two are involved in a steamy off camera affair, despite the fact that both are married to someone else.  

The two were spotted having dinner together on March 7^th at Laguna Beach and reports are that they looked very cozy together.

The two co-stared in the Lifetime channel movie, Northern Lights and have since hook-up.  Reps for neither star have confirmed or denied the rumor.

Cibrian has two children, ages 5 and 23 months with wife, model Brandi Granville.
