Who knew Taylor Swift could look THAT good in THAT LBD??
The country singer took to the Vegas MGM Grand Garden Arena stage last night in that backless frock. Joining Tim McGraw and Keith Urban for Tim's Superstar Summer Night, Tay Tay and the boys performed Highway Don’t Care — the same number they performed at the 2013 Academy of Country Music Awards just the night before!
Was the performance actually better the second time around?! We think, YES.
