Has Kristen Stewart had a breast augmentation?

It has been rumoured that Kristen Stewart has undergone a breast augmentation procedure. Speaking to Star, surgeons suggested the 22-year-old actress, who is best known for her role as Bella Swan in the Twilight films, has gone from a large A cup to a large B cup.The rumours started after Stewart was pictured at Comic-Con in San Diego, California, promoting the final instalment of the vampire movies with a larger looking chest than usual. Speaking to the publication, Michigan-based plastic surgeon Dr Anthony Youn said: “While this might be the result of a new, state-of-the-art bra, it’s most likely the result of a breast augmentation.” Dr Matthew Schulman, who is based in New York, agreed and said it looks as though the actress has gone up a cup size. A source who knows Stewart added that the actress has always hated having a small chest, but since having surgery she does not feel as though she needs to hide it any more. “She finally has the body she’s always wanted,” the insider added. The reports have not been officially confirmed or denied.
