LeAnn Rimes rocked in a sexy Santa dress during Sunday's Gay Men's Chorus of Los Angeles' annual Christmas musical extravaganza, titled Comfort & Joy.

The country music legend sang Rockin' Around the Christmas Tree and All I Want for Christmas is You in a revealing Santa dress as boyfriend Eddie Cibrian (CSI: Miami) and family members looked on, gay glossy The Advocate reported.

After a dress change, Rimes returned to the stage, where a single red rose sat on a lone stool in honor of gay teens who had been bullied to death, including 13-year-old Seth Walsh from nearby Tehachapi, California.

“We should all be loved for exactly who we are,” a tearful Rimes told the crowd before singing her final song, The Rose.

One-hundred-and-eighty students from nearby high schools received free tickets from the 180-member choir. Also putting in an appearance was Broadway star Sheryl Lee Ralph.

“I had THE BEST time!,” Rimes later tweeted her more than 93,000 followers. “Beautiful night. It was incredible. Such a funny show and several tears shed.
