Eddie Cibrian has hit back at rumours his marriage to Leann Rimes is on the rocks.

The 40-year-old actor, who has been married to the 31-year-old singer since April 2011, insists that all is well between them and their relationship is ''very functional.''

The 'Best Man Holiday' star told 'Entertainment Tonight' in a new interview that will air in the U.S. on Monday (04.11.13): ''[The rumours have] been going on for so long. They're just absurd, and to give any validity to any of these things, it's crazy.''

Eddie, who has two sons, Mason, nine, and Jake, six, with his ex-wife Brandi Glanville, also opened up about the couple's upcoming VH1 reality show.

He joked: ''We have such a great marriage, very functional and we just decided to do a show to screw that all up.''

Eddie and LeAnn went public with their relationship after it was revealed that they began an affair after starring in their 2009 Lifetime movie, 'Northern Lights' but rumours recently began swirling that they are headed for a $50 million divorce and Eddie has been reaching out to his ex-wife.

An insider told Star magazine: ''Brandi's always happy to let him unburden himself to her.''
