Taylor Swift stunned those in attendance at her show in Philadelphia on Friday night, bringing out two special guests to help her conclude her smash hit "Style."
As you can see in the clip above, model Cara Delevingne and actress Mariska Hargitay came out on stage (to thunderous applause) and threw their arms around Taylor while waving to the crowd.
Hargitay, of course, is one of Swift's major celebrity crushes. She has named one of her cats after the Law & Order: SVU actress.
Tweeted Swift after the show:
“Couldn’t even contain my happiness because @caradelevingne and @therealmariskahargitay surprised the crowd tonight. #1989TourPhilly.”
Delevingne and Hargitay both took part in Taylor’s Bad Blood music video, while the latter clearly had a blast at the concert, writing on Twitter:
"How awesome/gorgeous/fun are @taylorswift and @CaraDelevigne… #Justice #Catastrophe #Motherchucker #WeNeverGoOutOfStyle #1989WorldTour #PinchMeImDreaming #Wow #SerenadeOfMyDreams #TaylorMadeSerenade #TaylorMadeMoment #ThankYouTaylorIDontHaveWords."
