Islands in the stream -- that is what they are! LeAnn Rimes and Eddie Cibrian spent another Halloween together in coordinating costumes -- and this time, the country singer, 30, and her actor hubby, 40, paid tribute to two of country music's biggest icons: Dolly Parton and Kenny Rogers, who teamed up for the classic 1983 duet "Islands in the Stream."

To channel 80s-era Parton, 67, Rimes wore a curly blonde wig, black-and-white checked bandana, hoop earrings, skinny jeans, and a colorfully printed shirt unbuttoned to honor the "I Will Always Love You" singer's world-famous cleavage.

"'Happy Halloween and may you all find your 'Islands In The Stream' #Halloween'" Rimes wrote beneath a TwitPic; her husband of two-plus years morphed into Rogers, 75, with a shaggy beard, wavy brown hair, aviators, plaid shirt, leather vest, tight jeans and a silver-buckled belt.

A rep for Cibrian told Us Weekly on Wednesday that "there's absolutely no truth" to a new story in Star magazine that the couple are headed for divorce, and that Cibrian is "fed up" with Rimes.
