WATCH: Taylor Swift Sings ‘Trap Queen’ with Fetty Wap in Seattle

Taylor Swift was all “Hey, what’s up? Hello,” in between fangirling over Fetty Wap at her 1989 World Tour stop in Seattle, WA on Saturday (August 8, 2015). The pair performed what must have been a dazzling duet of “Trap Queen” for their audience of 60,000 fans.

Swift did not hold back her excitement on Instagram and Twitter, writing:

Commenting, “No big deal just the happiest moment of my life to date @fettywap,” she linked to a fan video of her and Fetty Wap’s performance:

Swift has consistently continued her tour of bringing celebrities, athletes and Billboard Hot 100 singers to the stage during her concerts, a stunt that’s including Nick Jonas, Jason Derulo, Cara Delevingne, Kendall Jenner, Mariska Hargitay, Serena Williams, the Women’s National Soccer Team, Lorde, and many, many more. 

And the fun didn’t stop there. During “Style,” Ciara and boyfriend/Seattle Seahawks golden boy Russell Wilson strutted out on stage for their turn.
