Taylor Swift: Butt Implant Rumors Circulate Following iHeartRadio Music Awards 2016 Appearance

After months of rumors about Calvin Harris pressuring Taylor Swift to get a bigger backside, the "Bad Blood" singer looked noticeably curvacious at the iHeartRadio Music Awards on April 3. Swift's derriere certainly looked more firm and perkier than usual compared to her photos from just a year ago.

Swift gushed about Harris in her acceptance speech for Best Tour, but her appearance on the red carpet had many fans wondering if she should also credit her boyfriend for her sudden bigger butt.

"For the first time I had the most amazing person to come home to when the spotlight went out and when the crowds were all gone. So I want to thank my boyfriend Adam for that and I love you guys so much," Swift said.

According to National Enquirer, “Calvin’s always preferred really toned girls," an insider revealed. "While there’s not an inch to pinch on Taylor, he wants her to get more bootylicious!”

The chart topper arrived in a catsuit that flaunted her curves, pulled from Saint Laurent's autumn/winter 2016 collection. The form fitting one-piece featured a halter neckline and was covered in sequins. It was also cinched at the waist with an oversized patent leather belt.

The National Enquirer source noted that Swift has been obsessively hitting the gym in hopes of building a better butt, But how did the 26-year-old hitmaker pull a booty out of thin air?

Fans rushed to Twitter to speculate, some say she may just be wearing butt pads. However, many fans believed that Swift did something drastic and chose the unnatural alternative -- butt implants.
