It looks like Niall Horan and Selena Gomez may end up in front of the altar! The One Direction hunk had a serious confession during their band's carpool karaoke with James Corden. Horan confessed that he wants to marry his rumored girlfriend, Selena Gomez.

On Tuesday, One Direction band members joined Corden in "Late Late Show" for its segment Carpool Karaoke where they roamed the streets of Los Angeles. The funny host asked the group to play a modified version of "Shag, Marry, Kill" which was turned to "sleep with, marry, and go on a cruise with." The choices included Selena Gomez, Demi Lovato and Tina Fey. When it was Horan's turn to respond, he said that he would marry Gomez, Entertainment Online reports.

"Sleep with Tina Fey, let's marry Gomez and go on a cruise with Demi Lovato. Great voice, we could be singing songs," Horan, 22, candidly answered Corden.

It was the first time that the former "X Factor" contestant gave a hint on his controversial relationship with Gomez. Although the "Good for You" singer slammed their dating rumors just recently, multiple media sites can't get enough of the two, who are frequently seen together, Daily Mail reports.

It was on Friday, Dec. 11 during Billboard's Women In Music 2015 event in New York City when Justin Bieber's ex claimed that she and the 22-year-old British singer are just friends.

"Oh my God, no! I love him, I always have. He's amazing," Gomez answered.

Hollywood Life reports that the reason why Horan and Gomez continue to deny their romance is because they're not in a rush to claim it. According to the site, the rumored couple started dating in December. They were reportedly enjoying it by not putting labels on their relationship as they are still young.

Do you think Niall Horan and Selena Gomez's romance is just for show or is it real?
