Jason Kelce Called Taylor Swift's ‘Brother-in-Law' During Surprise WWE Appearance

Jason Kelce takes on the WWE! The newly-retired NFL star made a surprise appearance at Wrestlemania on Saturday. Jason walked into the arena in disguise wearing a luchador mask. When he ripped it off, one announcer asked, 'Isn't that what's-her-name's brother-in-law?' Pat McAfee, who was also serving as a commentator, then burst into a few bars of Taylor Swift's 2013 hit, '22.' The singer's dating Jason's brother, Travis Kelce.
