After teaming up with Kendrick Lamar for her Bad Blood remix, Taylor Swift is apparently further extending her rap network. Last night the singer held the first of two sold out nights at Chicago's Soldier Field football stadium for her 1989 World Tour, and in attendance was Chance the Rapper and his crew. According to the above Instagram from Mike Ahearn, Swift was apparently telling Chance how big of a fan she was before Ahearn snapped the photo. Now the question is, what's her favorite song off Surf? And is it too late to finesse a T-Swift feature on that new joint album that Chance and Lil B just cooked up?
