Country star LeAnn Rimes is planning a candid tell-all about the break-up of her first marriage and her romance with new husband Eddie Cibrian.

The couple made headlines in 2009 when an on-set romance during the filming of TV movie Northern Lights continued after the cameras stopped rolling.

Rimes and Cibrian, who were both married to other people at the time, were caught on a security camera kissing over dinner at a restaurant.

The affair ended both their marriages and last year, the couple wed.

Now E! News reports the 29-year-old singer's representative has been "putting out feelers" to find the right person to help write her autobiography and "tell LeAnn's side of the story in her own voice".

A publishing source says she "wants it to be a very honest book so she can speak directly to her fans and tell her side of the story. She's been through a lot of changes over the past few years and this is her chance to speak candidly to her fans."

Ironically, Cibrian's reality TV star ex-wife, Brandi Glanville, is also planning to write a book about her split from the actor.
