Taylor Swift surprised fans at a Massachusetts concert when she invited out singer Hayley Kiyoko onstage for a queer AF duet.

Swift, who's currently on the road for her Reputation World Tour, performed in Foxborough, M.A., on Thursday. The "Delicate" singer is known for inviting her friends onstage, but fans were unprepared for last night's cameo: Toward the end of the concert, she invited an unannounced special guest—none other than Hayley Kiyoko—to take the stage with her.

The pair gave the crowd a show-stopping rendition of Kiyoko's hit single "Curious," much to the delight of the singers' mutual fans around the globe, who took to social media to share their excitement. (For Kiyoko, the moment was a big deal, too, marking her first performance at a stadium.)

In case you needed proof that Kiyoko is actually "Lesbian Jesus," look no further: Earlier this year, the #20GayTeen queen told NewNowNext that she's "honored" to be a role model for young queer women.
