Taylor Swift Butt Gives??? Suddenly Packing More Back

Taylor's lady lumps were majorly on display at the iHeartRadio Awards over the weekend as she showed up in a skintight black bodysuit. We did some deep research, checking out a bunch of Taylor butt shots from the last year ... and she's definitely shown some growth.

Butt pads? Squats? Who knows?

We're sure of one thing -- Calvin Harris ain't complaining.
