The musician and the TikToker, both 18, attended the MLB All-Star Game at Dodger Stadium in Los Angeles July 19. Joined by her parents Heidi D'Amelio and Marc D'Amelio, as well as by Fanatics CEO Michael Rubin, Charli and Landon watched the American League beat the National League with a final score of three to two.
While it's unclear which team they were rooting for, one thing is for sure: Landon and Charli are fans of each other. So much so, in fact, that the social media star later posted a photo of Travis Barker's son wearing a "Charli Fan" T-shirt with hearts.
A source confirmed to E! News in June that Charli and Landon are in the "early stages of dating." Over the past month, the two have been spotted on several outings together. For instance, Charli attended the launch of Landon's boohooMAN collection in Hollywood, Calif. June 14.
