Did Christina Aguilera get breast implants?

Christina Aguilera has once again sparked rumours of going under the knife.

A scar under her arm was apparently spotted when she waved to her fans a press conference for her new film, ”Burlesque,” in Tokyo, reports the Daily Mail.

The small line could be the result of a transaxillary endoscopic breast augmentation- a breast enlargement technique where implants are placed through an armpit incision.

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.

Aguilera”s decolletage has certainly increased over the years, and while could be the result of carrying more weight.

Her new flick is a song-and-dance extravaganza about a small-town girl trying to make it big.
