Reported exes Harry Styles and Kendall Jenner were on James Corden’s The Late Late Show last night and played a rousing game of “Spill Your Guts or Fill Your Gut,” in which participants must answer a personal question or consume some decidedly unappetizing food.

Styles kicked off the game by asking Jenner to rank her siblings in order from best to worst parent. Jenner replied that Rob Kardashian was the best and Kourtney Kardashian was the worst (with the caveat that they are all “amazing”). Jenner then asked Styles which of the songs on his 2017 self-titled solo album were written about her. “I’m dying to know this,” she said. Styles chose to eat cod sperm rather than respond.

Styles and Jenner were presumed to be dating back in 2013/2014. They were photographed vacationing together in the Caribbean, but neither the singer nor the model ever commented publicly on the relationship.

“It’s not like I’ve ever sat and done an interview and said, ‘So I was in a relationship, and this is what happened,’” Styles recently told Rolling Stone. “Because, for me, music is where I let that cross over. It’s the only place, strangely, where it feels right to let that cross over.”
