LeAnn Rimes is showing off her sexy side (again) wearing a skimpy Santa outfit that she posted on Twitter.

"Santa's Elves and Me!!" Rimes tweeted, showing off her photo with the Gay Men's Chorus of Los Angeles. On Sunday, the 28-year-old singer sang "Rockin' Around the Christmas Tree" and "All I Want for Christmas Is You" for the group's annual Christmas show.

Rimes struck a few sultry poses in the outfit and tweeted "Mrs. Clause [sic] at your service!" with the attached pictures.

Rimes has been baring a lot this year. In October, she graced the cover of Shape magazine in a tiny red bikini and in August, she danced in a vintage bikini on stage during an America's Got Talent performance.

Last month she wrote that she and boyfriend Eddie Cibrian were not engaged and wished ex-husband Dean Sheremet well on his new engagement.

Do you think Rimes is sharing too much on Twitter?
