Taylor Swift is revealing what Travis Kelce said to her before proposing in August. The Grammy winner, 35, joined host Jimmy Fallon during the Monday, October 6, episode of The Tonight Show, stepping onstage in a metallic sequined minidress and sparkly platform heels. She briefly spoke about her brand-new album, The Life of a Showgirl, before Fallon, 51, congratulated the pop star on her recent engagement to Travis Kelce after two years of dating. "Taylor, that is insanity," Fallon said, admiring the massive diamond ring that Kelce, 36, slipped on Swift's finger.
