Christina Aguliera, the occasionally curvaceous pop star, has shed 49-lbs and is feeling sexier and more seductive than ever; which is evident in a snapshot taken from her "Unforgettable" perfume commercial, where she is seen wearing a white-hot number. She tweeted the photo on Tuesday, October 15th.

"Feeling sexy & seductive on set with Mark Liddell filming," she stated in a caption for the saucy photo. While we've yet to see the commercial, we've seen enough to know that X-Tina looks amazing as she embraces her new sleek look. The white dress that she wears is a snug slip of fabric with a frisky diamond-cutout on the back. Aguilera pairs the dress with stellar glittered kitten heels.

Aguilera, 32, says that her weight loss was not difficult at all. She simply limited her intake of alcohol, and she stayed away from unhealthy foods. For breakfast she ate blueberries, turkey bacon and half an avocado; she snacked on celery with almond butter, lean chicken breast over veggie-heavy salads and shrimp cocktail; and for dinner she enjoyed chicken or fish curry and brightened the meal with a glass of wine.

The "Beautiful" singer took her newly slim body to Maxim Magazine which featured her on the cover of their October issue.

The Voice coach/judge indicated to Maxim that while she might be radiating sexiness, she isn't doing it on purpose, claiming to be a "down-to-earth girl" who likes to lounge in just "a jersey and boy's underwear." She also made a point of saying that trying too hard to be sexy is the worst thing that a person can do. It should be effortless.
