Back in October, The Voice coach Christina Aguilera flaunted her bodacious bod while filming an ad for her perfume, “Unforgettable." As she tweeted back then, “Feeling sexy & seductive on set with Mark Liddell filming.”

Just in time for Christmas, the sexy songstress tweeted another photo that depicts her spraying perfume on herself with the caption that simply read, “#Unforgettable.” The photo is dimly lit so it’s hard to see what she’s wearing, but it looks to be a super sultry black, low-cut dress and her hair seems to be an ode to Marilyn Monroe.

Although she has worn some demure styles on The Voice this season, she’s also gone the sexy route, showing off her newly-svelte frame. Can you blame her? As the “Say Something” singer told Jay Leno in an interview on The Tonight Show a while back, “I’m 32 and feel sexier than ever!”

The vocal powerhouse recently celebrated a birthday, and let’s just say 33 is looking pretty good on her. Like many celebs, however, Christina has had to fight rumors that she got plastic surgery to lose the weight. Those on her inner circle insist she lost it the old-fashioned way — through diet changes and exercise. In fact, a friend told Life & Style recently about some of the ways Xtina stays slim.

“Christina takes her lunches and snacks with her to work now, so she can watch how much she eats instead of overindulging in anything bad for her,” the friend revealed via Hollywood Life. “She eats carbs, protein, snacks like pretzels — she just watches how much she eats.”
