During Christina Aguilera’s rise to fame in the nineties, she was subjected to criticism about her body and some even said that she enhanced herself via plastic surgery. I didn’t see any sign of that, at the time, as Christina was gaining her “Genie In A Bottle” popularity.

Some said the same thing about another pop star, Britney Spears. The curious speculated that the two of them had some work done.

We don’t have anything on Britney, but the photo above just may prove that Christina has gotten an upgrade. During her promotional duties for “Burlesque” in Tokyo earlier today, Christina raised her arm to greet visitors and fans and revealed a nasty scar in her right armpit.

NY Daily News reports:

The incision is a common sign of transaxillary endoscopic breast augmentation, according to the Daily Mail, where implants are inserted through the armpit.

The 29-year-old mother of one has never directly commented on the rumors that she may have had a boob job, but Aguilera seemed hardly concerned at the event about potentially revealing her secret.

The singer, who turns 30 later this month, happily posed with a birthday cake while her co-stars, Kristen Bell and Cam Gigandet, clapped.
