Christina Aguilera is allgedly the latest victim of too much airbrush editing after a new ad for NBC's "The Voice" circulated on Thursday. The advertisement shows the singer -- often criticized for her weight -- appearing dramatically slimmer, leading many to believe the photo was heavily photoshopped.

Aguilera is seen in the ad for season three of "The Voice" wearing a black and white striped dress over a svelte figure in front of dressing room lights. After a year of her weight being analyzed, it appears that Christina has either toned up drastically, or was digitally edited.

"Christina Aguilera is one attractive woman, but the airbrushing she gets in these two new promotional shots for 'The Voice' makes her borderline unrecognizable," The Hollywood Gossip wrote.  "We'll never quite understand the need to doctor images of someone so pretty already...but such is life for PR folks."

"Christina Aguilera appears to have mastered the art of shifting a substantial number of pounds overnight. Or could that be thanks to the magic of photoshop," The Daily Mail wrote adding that "one thing that looks different is the petite thighs and waist in contrast to the silhouette she has been showcasing in recent months."

The Daily Mail pointed out that Aguilera did not look nearly as thin in person days before the ad emerged during a press junket and cocktail reception in Los Angeles at the home of Mark Burnett on Sunday.  Wearing black leggings, a black-and-white tribal printed dress, a leather jacket and Christian Louboutin heels, the blonde bombshell appeared to still be harboring the weight she put on since her divorce from Jordan Bratman.

Toofab.com, however, believed Aguilera looked so good in the ad "thanks to some great makeup, slimming dress" before adding "and maybe just a little bit of Photoshopping."

Criticism for Aguilera's weight poured in after her performance at "Michael Forever" in October last year. Despite being called "plus-size" by radio personality Howard Stern, she said she is happy in her own skin despite what the critics are saying.

"As long as I'm happy in my own skin, that's all I need. I'm happy with where I'm at. I have a boyfriend that loves my body. I love my body," Aguilera said. "Women, we are definitely under a microscope, and under massive scrutiny. You got to be strong, powerful, very confident woman."

The singer hasn't only gotten criticized for her weight gain and fashion faux pas in light of the extra pounds; After a performance at Etta James' funeral in January, Aguilera made headlines for sporting a risqué cleavage-bearing dress with an odd brown substance dripping down her leg, which some believed was "period blood."

Whether she was Photoshopped or not, Aguilera isn't the only star to appear drastically different in promotional photos and ads.

Kim Kardashian has been lambasted in the past for allegedly relying too heavily on Photoshop and nearly completely altering her looks. In March, the three Kardashian sisters, known for their sexy curves, appeared in an advertisement for their Kardashian Kollection Swimwear showing flawless skin. However, the photographer, did not admit to any editing on the photo.

The most infamous incident, however, was in 2009 when an image for Complex magazine circulated showing Kardashian without Photoshop. The magazine published heavily edited image covering the star's natural cellulite, which angered the starlet.

Kardashian responded to the Photoshop controversy by tweeting the original photo.

"So what: I have a little cellulite," Kardashian wrote in a blog entry entitled "Yes, I am complex!" "What curvy girl doesn't?!" "I'm proud of my body and my curves and this picture coming out is probably helpful for everyone to see that just because I am on the cover of a magazine doesn't mean I'm perfect," Kardashian says.

On the flip side, unphotoshopped photos have become popular lately, after some supermodels including Gisele Bundchen, Heidi Klum, Adriana Lima and Alessanda Ambrosio were seen in unedited images and circulated around the net. The photos, which were the casting photos for Louis Vuitton's Fall 2010 runway show, were posted on Reddit and went viral.
