TAYLOR SWIFT showed off some serious cleavage at the "People's Choice Awards"earlier this month.  But  she may have also showed off something else:  A BREAST IMPLANT SCAR.

It's not official that Taylor has newbies . . . but she is looking a little  fuller.

And "In Touch Weekly" found a picture  of Taylor's cleavage in which something that COULD be an implant scar is  visible.
