Christina Aguilera has once again sparked rumours of going under the knife.
Aguilera, in Tokyo Tuesday to promote her film “Burlesque,” raised her arm to greet spectators, revealing a scar in her right armpit.
The incision is a common sign of transaxillary endoscopic breast augmentation, where implants are inserted through the armpit.
Experts said the popular method usually leaves an inch-long scar and is the preferred option for patients who want to avoid scars on the breast.
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.
