Taylor Swift Reignites Breast Implant Rumors With Low-Cut Fashions

Taylor Swift sure looked hot last night at the 40 Principales Awards in Madrid.

Unfortunately, her two ensembles for the evening have once again sparked speculation on the Web that she's gotten breast implants.

First, Swift arrived in a plunging-neckline white dress and then performed in a body-hugging red top.

Even so, there's nothing fake about her figure. Swift has not gone under the knife to enhance her chest, a source tells E! News.

Back in April, a slew of celebrity tabloids set off a round of rumors when a tight-fitting dress she wore made her bosom appear bigger than usual.

Then the guessing game was reignited earlier this month when she appeared at the People's Choice Awards in a surprisingly low-cut white gown.

So, now that that rumor-busting is off our chest, we can't wait to see what she wears next month to the Grammys.
