Kendall Jenner and ex Devin Booker had some playful banter after her Fanatics ad campaign dropped before Super Bowl LX. The back-and-forth started after Jenner, 30, appeared on the Wednesday, January 28, episode of The Tonight Show Starring Jimmy Fallon and gave her official pick to win the Super Bowl. (The Seattle Seahawks will face off against the New England Patriots in the championship game next month.) "I feel like I'm going to go with my gut here ... I'm going to go with the underdog, and I feel I'm gonna go Patriots," the model told host Jimmy Fallon.
