The Taylor Swift BFF tour – better known as Swift’s 1989 tour – continued on Friday night, as Swift brought “Bad Blood” video co-stars Mariska Hargitay and Cara Delevingne out on stage during her Philadelphia show.

“Couldn’t even contain my happiness because @caradelevingne and @therealmariskahargitay surprised the crowd tonight,” Swift wrote on Instagram. As Swift has done previously, her friends came out during a performance of “Style.”

Hargitay posted video of her appearance to Instagram, using the hashtags #Unreal, #AmazingShow, #IncredibleNight, #1989WorldTour, #ThankYouPhilly, #ThankYouTaylor, #Gracious, #Graceful, #ClassAct and #YouNeverGoOutOfStyle to express her excitement.

Hargitay also thanked Delevingne for help with her eyebrow game.

Swift’s back in Philadelphia on Saturday night for her next 1989 tour show. Maybe this one will include Ellen Pompeo?
