She's single again!
Allegedly, this video was taken in early August when they were VERY much together.

If you're in need of some Christmas cheer then we've got just what you're looking for!
The new wifey and momma-to-be brought her red sparkles with her as she performed Underneath the Tree on the show, and she seriously pumped up the holiday spirit!
Although, we're guessing her former American Idol judge, Simon Cowell, didn't find anything cheery about her rocking the stage of a competing show. Perhaps he's feeling a little Grinch-like over on X Factor today! LOLz!
You already know we LOVE her voice, but her fun Christmas songs are too cute for words! We think she's got a few future classics on her hands!
Ch-ch-check out the fab performance (above)!
