She's a fighter! After harsh criticism for her weight during her first three seasons on The Voice, pop diva Christina Aguilera has slimmed down for her comeback in season 5 (after taking off season 4), and boy, is she ready to show off her trim physique. 

In the Nov. 11 live shows episode of The Voice, Xtina, 32, wore a black Versace form-fitted dress with a high neckline and leather studded details on the shoulders and around the waist. On the "Your Body" singer's website, her stylist Simone Harouche broke down the svelte look: "For tonight's chair look, we wanted to go with a sleek and edgy vibe." 

The Grammy winner is known for sporting heavy makeup and bright colors, but on Monday night she rocked a more natural look.

As usual, the opinionated pop star gave her blunt perspective on each contestant's performance, but she was most critical when it came to fellow coach Blake Shelton. The country crooner gushed over his smooth artist Ray Boudreaux's performance of John Legend's "All of Me" until Aguilera chimed in. 

"Blake has quite the crush. Lil' creepy," she joked. "These ladies were loving it; Blake was obviously excited. Blake was getting his panties in a bunch!"
