James Corden makes Niall Horan choose between exes Selena Gomez and Ellie Golding in gross-out game

Amicable exes! Niall Horan briefly dated singer Ellie Goulding in 2013, but he still thinks fondly of the British songstress. In a game of Spill Your Guts or Fill Your Guts on Wednesday's Late Late Show, the former One Directioner was questioned about some of his famous exes by host James Corden.

"Niall, you've dated both Selena Gomez and Ellie Goulding. It's your last night on Earth, out of the two of them, who would you rather spend it with?" Corden asked, revealing that if Horan didn't answer the question, he and partner Isla Fisher would be forced to eat beef tongue.

"Because it's the last night on Earth, Ellie is a big fan of Planet Earth by David Attenborough, so I would sit and watch that with her. For that reason, Ellie Goulding," Horan, 23, replied.

In fact, this isn't the first time Horan has recently praised the "Burn" singer. In a lightning round game of "Who'd You Rather?" on The Ellen DeGeneres Show earlier this week, Horan picked Goulding above Diane Keaton, Rita Ora, Jennifer Lopez, and Kendall Jenner, making her the winner.

"We're still friends," Goulding, 29, told Seventeen in April of her relationship with Horan. "We went on a few dates, and it was really fun. He's a really, really lovely guy. He's got the biggest sense of humor, he's very caring, and I see him as a genuine friend in the industry."

Corden didn't just make Horan pick between his exes, he also questioned him on which member of One Direction was his least favorite. But instead of answering, the singer opted to drink a disgusting salmon smoothie. Watch the clip to see the horrific moment!
