Harry Stylesis keeping tight-lipped about potentially penning lyrics about former girlfriendKendall Jenner.

When it came time for the “Lights Up” singer’s first question, the audience roared over the awkward position it put the singer in: tell hisformer flameshe inspired his music or eat a plate of cod sperm.

“Which songs on your last album were about me?” Jenner said, cheering along with the audience after reading off the random card.

Without comment, Styles tucked a napkin in his collar and grabbed some utensils to dig into the cod sperm rather than answer the question. Hesitant after examining the dish, the singer said, “So I’d say track uh um …” before continuing to pick at his plate, preparing himself to go through with it.

“Just don’t look at it,” Jenner offered in solidarity, to which Styles joked sarcastically, “Oh yeah, that fixes everything, just don’t look at it!”

Attempting to steel himself for the taste test as his ex across the table laughed, Styles tried to talk himself out of the situation, asking, “What are we doing?”

“This was your idea,” Jenner pointed out.

The formerOne Directionband member then quickly forked the cod sperm into his mouth, chewing the item while trying to mask his presumed disgust.

“It really carries an aftertaste,” he said with a laugh.

Later in the segment, when faced with ranking thesolo music careersof his former boy band mates, Styles again declined to answer, this time having to stomach a bite of giant water scorpion.

Theon-and-off romancebetween Styles and Jenner first began when they were spotted grabbing dinner in November 2013, solidifying dating rumors the following January when they went snowboarding together.

Over the following year, there were seen on trips together and stepping out for dinners, though a source told PEOPLE in 2016 that things “never got serious” between the two.

That same year, Jenner’s sisterKhloé Kardashianspoke about the couple, unable to clearly define their relationship status.

“They were hanging out together. Do I think they’re dating? Yes. I don’t know if they’re like boyfriend-girlfriend. Nowadays, I don’t know, people are weird with stuff. So I don’t know their ‘title,’ Kardashian toldEntertainment Tonightat the time, using air quotes. “But I mean, they were in St. Barts together hanging out, so to me that’s dating. I would call that dating.”

Though they werespotted flirtingat theMet Galaearlier this year, a source assures the two are not an item at the moment.

“Harry was her first real relationship, so there is a lot of history there,” said the insider, “but they’re just friends.”
