Christina Aguilera’s weight loss program is working. Christina Aguilera showed off her slimmer, sexier self in a low-cut little black dress that showed off her famous curves on the “Tonight Show” on Wednesday.

“The Voice” coach and singer Christina Aguilera told Jay Leno "I'm 32, and I feel sexier than ever, just because you know what you want."

Christina Aguilera showed off her new figure in an upcoming Maxim pictorial. Christina Aguilera talked about her weight-loss saying it wasn’t hard work. For the Maxim shoot, Christina Aguilera said her approach was "effortless sexy —- not trying too hard."

Christina Aguilera told Maxim, "I've never been one to shy away from my sexuality." On the “Tonight Show,” she said "I'm an artist, and expressing myself in a sexual way, no matter how that changes throughout the years, is something that has always come naturally to me. At this point of my life, I'm 32 and I feel sexier than ever because you know what you want. So it was all about -- the shoot, yes I was in control of that -- but it was all about appreciating the woman I've become, and effortless sexy, not trying too hard."

Christina Aguilera may be a control freak about a lot of things in her life, but her sexier self allows her to let go in more places than just a photo shoot. Christina Aguilera said "I'm a stickler about organization: everything needs a place, a purpose. I think every woman should relax and allow herself to be pleased in the bedroom. It's the one place I can let go."

Christina Aguilera also dished on Adam Levine. The “Genie in a Bottle” singer said the two singers “don't hate each other.”

“The Voice” returns for Season 5 on Monday. Blake Shelton and Adam Levine will join original coaches Christina Aguilera and CeeLo Green in the new season.

Christina Aguilera took some time off to spend some quality time with her 5-year-old son Max and to do charity work in Rwanda with the United Nations. Christina Aguilera said "The time off made me see more than ever that [the competition] isn't about us. It's about the contestants."

Christina Aguilera and Adam Levine had some heated moments in the early seasons.

Christina Aguilera said "We're both very passionate, but it isn't personal with Adam. It never has been. We're just very strong personalities."

“The Voice” hasn’t had a breakout singing star the way “American Idol,” but Christina Aguilera thinks that could change. Christina Aguilera believes this could is could "absolutely" be the year. She says "To me, being on the show [and] gaining advice from all of us who have lived this business, that is success."
