In Touch Weekly is claiming LeAnn Rimes is really going all-out for her wedding, with a source saying "it’s like she [Rimes] thinks she’s Kate Middleton and Eddie is Prince William!"

The magazine found an unidentified friend of the couple who would talk about the wedding arrangements. That friend says Rimes has three dresses for the big day--"one to walk down the aisle, one for the dinner and another to dance in.”

The source also added that Rimes "has been working out nonstop."
