Christina Aguilera has slimmed down after her tremendous weight loss in 2013. The "Hurt" singer is confident with her skinnier body, saying she "feels sexier than ever" with her new curves to Jay Leno.

According to Hollywood Life, the platinum blonde songbird revealed her thinner body on the "The Tonight Show With Jay Leno" on Wednesday.

The singer may have there to promote "The Voice's" fifth season, but her skintight dress stole the show. Aguilera flaunted her great figure in a black Bec & Bridge dress with a very daring plunging necklace to show off her amble cleavage.

The singer paired the super-sexy dress with Christian Louboutin black high heels to accentuate her toned legs. Aguilera made quite a statement by wearing the little black dress, proving that she has been hitting the gym and working out during her break from the NBC singing competition.

Aguilera didn't hestiate to tell Leno that she feels more sexy now than ever before after her hard work has paid off with dropping more than 25 pounds recently.

And she is showing off her hot body every chance she gets these days. The "Beautiful" songstress just did a cover shoot for Maxim, highlighting her signature bold blonde locks, tanned skin and more curvaceous shape.

HL reported that Aguilera played the part of a beach babe very well during the shoot.

"The Voice" coach rocked a look with girly curls, a black smokey eye and long lashes on Maxim's cover. She also had a bright-red, super-shiny pout and very feminine pink nails.

Her whole Maxim look was very pretty and sexy, said HL's Dory Larrabee.
