Swift, 25, and Gomez, 23, duetted the brunette beauty's "Good for You" on the stage as they flaunted their tones legs in shorts.
While Tay Tay wore a custom white bustier and short shorts, Selena Gomez opted for a black studded plunging neckline top and shorts both by Norma Kamali.
Celebrating their friendship, the girls hugged and had fun on the stage after the performance. Gomez even shared a
pic saying, "After nearly 8 years of friendship, I just can't wait to tell our kids we ACTUALLY got to perform in front of thousands of insanely beautiful people together. TWICE! I love you Tay. #bestnightEVER #whatISlife."
Apart from Selena Gomez, Tay Tay's all time big crush, Justin Timberlake also gave a visit and the duo performed his 2013's hit single, 'Mirrors'.
After parading out a never-ending stream of celebrity guests during her 1989 World Tour, the Grammy winner at last invited Justin Timberlake to make history and perform together for the first time.
Back to 2008, Timberlake and Ellen DeGeneres surprised a 19-year-old lovestruck Taylor on-air on The Ellen Show and we had been waiting to see their collaboration until now.
