Not even Harry Styles can play it cool when someone mentions his ex-girlfriend, Kendall Jenner.

On Monday, May 15, the former One Directioner was questioned about the model while appearing as a guest on The Late Late Show. The singer was interviewed alongside actor Aaron Taylor-Johnson, who revealed that he and his wife have chickens named after the Kardashian family.

"I think the first two [that died] were Kim and Khloé," the 26-year-old explained. "There's Kylie, Kendall, Kourtney, Khloé, Kim, Kris, and Caitlyn. And they are called the Kardash-ikens."

After hearing Kendall's name, Harry hilariously reached for his mug before playfully raising his eyebrows, as if anticipating what was coming next.

"And they lay every day," Aaron added, causing the 23-year-old to roll his eyes and reach for his drink again. "Do they lay every day, Harry?" host James Corden asked, though the handsome performer refused to answer.

Kendall and Harry first sparked dating rumors in 2013, and were then spotted getting cozy together in late 2015 while on vacation in Anguilla.

The 21-year-old reality star isn't the only one of Harry's exes to come up in recent days. In an interview with Rolling Stone, the Brit talked about his highly-publicized romance with Taylor Swift. "I think relationships are hard, at any age," he said. "And adding in that you don't really understand exactly how it works when you're 18, trying to navigate all that stuff didn't make it easier."

He continued, "I mean, you're a little bit awkward to begin with. You're on a date with someone you really like. It should be that simple, right? It was a learning experience for sure. But at the heart of it — I just wanted it to be a normal date."
