Swift commemorated the experience on her own Instagram, writing, "Oh what a night."
After a rousing acceptance speech calling out Kanye West, Swift and BFF Selena Gomez hit the GRAMMY parties to celebrate, along with more of the squad. The "Out of the Woods" singer wore a provocative gold and ivory miniskirt and tube top for her night on the town.
ET spotted the 26-year-old star at the Universal Music Group's 2016 GRAMMY after party at the Ace Hotel, though she stayed "no more than five minutes." An eyewitness told ET that Swift exited through a side door of the hotel's theater around the same time Bella Hadid and her beau, The Weeknd, were spotted in the lobby.
The Grammy-winner was joined by Harris -- who went with a simple t-shirt and jeans look -- at the Republic Records GRAMMY Celebration at Hyde Sunset Kitchen, along with Lorde and Ellie Goulding, where the couple was able to sneak in a kiss!
