Taylor Swift's
showing off all of her hard work at the gym!

The blonde beauty showed up to the 2014 MTV Video Music Awards on Sunday in Los Angeles, wearing one of the sexiest outfits we've ever seen on her.

Rocking a baby blue long-sleeved jumper -- which showed a ton of leg and even some booty -- the "Shake It Off" singer looked amazing on the red carpet.

Swift finished her look with a bold red lip, smokey eye and maroon booties.

The 24-year-old also posted a pic via Facebook of her getting ready for the award show with bestie Ed Sheeran.

In the cute candid, the "Red" singer's pretending to put makeup on the "A-List" crooner. "We're getting ready for the #VMAs, are you?," she captioned the funny photo.
