Fans attending Taylor Swift's July 10th show at MetLife Stadium were in for a surprise.
After being in New York earlier in the day for their ticker-tape parade, members of the United States Women's Soccer Team joined Swift on stage during her performance of the song "Style."
America's Got Talent judge Heidi Klum also made her way down the runway during the show with the team. They celebrated by waving American flags, and even let Taylor raise the World Cup trophy herself.
But they weren't the only stars to make a guest appearance. Singer The Weeknd joined Swift onstage as the two performed his new hit single "Can't Feel My Face."
And just when you think it couldn't get any more exciting, four stars from Swift's "Bad Blood" music video made their way onto the catwalk. Gigi Hadid, Lena Dunham, Lily Aldridge, and Hailee Steinfeld appeared onstage in their outfits from the video.
