Don't Miss:

The X-Factor contestants battled live on stage for the first time this week, and Britney Spears dressed up to take her seat at the judges’ table. The pop star donned a short black Lever Couture dress for Wednesday’s performance show, and chose a Lublu dress collar style for last night’s results show. She accessorized the latter with Marni earrings, a Kelly Wearstler ring, a BCBG necklace, and a belt from Mango. We can’t wait to see next week—for the performances, too, of course!

Plus, see all of Britney’s changing looks!
