There's no denying that Swift is looking bustier these days, and according to In Touch magazine, it's because she went under the knife in April.  A plastic surgeon, who has never treated Swift, claims the singer has gone from an A cup to a B cup.

"You can see the implants," Dr. Michael Fiorillo told the magazine after looking at a photo of Swift from the People's Choice Awards.

It's not the first time that such rumors have made the rounds. Back in April, when Swift allegedly underwent the surgery, HollywoodLife spoke to three plastic surgeons, who also never treated the singer, who all agreed it appeared as though she had some surgical enhancement.

The singer has yet to comment on the rumors, so it's up to you to decide if you believe she went under the knife or if gravity is simply on her side.
