LeAnn Rimes has reportedly split from her husband.

The 26-year-old star - who has allegedly been romancing her co-star on TV movie Northern Lights Eddie Cibrian – referred to her troubled marriage to dancer Dean Sheremet during a performance at Utah's Deer Valley Music Festival on Saturday.

The singer-and-actress told the crowd: "You know, I think that you will all really be able to relate to this next song in your lives. You probably know it's inevitable that in a relationship, sometimes you will have your heart broken at some point.

"Sometimes, you might say that you can't do anything and sometimes, you want revenge. Sometimes, you say, 'You're not worth it.' But sometimes, you don't, and that's when you leave it in God's hands and know that he will take care of it."

Dean has also spoken about the end of his seven-year marriage, taking to his Twitter blog to let fans know he was dealing with the break-up.

He wrote: "Thanks to everyone for all the support through a very difficult time!"

It has been claimed the couple decided to part ways because their lives were going in different directions.

A source said: "They were so young when they got married, she was 19, he was 21. Maybe they just grew up and they weren't in the same place anymore. I don't think that's unusual considering how young they were when they got married, and the business they're in."

Another insider explained: "LeAnn and Dean have been separated for quite some time now, but they're continuing to try and work through their relationship."

Rumours LeAnn and Eddie were having an affair began circulating in March, after the pair were allegedly caught on security camera kissing and holding hands.

Eddie vehemently denied the affair rumours, saying: "Other than being friends and two actors who were romantically intertwined in a movie-for-TV we filmed last fall, there is no truth to the reporting. It is a fabricated story that is using random snapshots as connective tissue to create a scandalous relationship."

However, earlier this month they were spotted flirting and laughing at a friend's Malibu home before going on a motorcycle ride together.

It also emerged Eddie's wife Brandi Glanville - who has two children with the actor, six-year-old Mason and Jake, two - had left him.

Brandi confirmed: "Eddie and I have decided to take some time apart. I want to do what is best for our children. Eddie and LeAnn deserve each other."
