We knew Katy Perry was likely getting engaged sometime soon but we never figured it be to a boy band member! One Direction’s Niall Horan announced his “engagement” to the “Roar” singer after they met up in Tokyo.

Niall “proposed” back on October 20, tweeting “I love you @katyperry ! Thank you! Ps . Will u marry me?” Once the 20-year-old boy bander and Katy finally got a chance to meet up face-to-face, it sounds like the recently 29-year-old had her answer ready to go.

“she said yes ! It's happening! Haha,” Niall shared November 1. As of publishing, it’s unconfirmed how many 1D fans burst into tears upon reading that message.

Niall’s never kept his feelings for Katy a secret. The two actually go way back to 2010 when Katy cast the deciding vote that put Niall through to boot camp on The X Factor UK and thus ultimately secured his spot in 1D.

You might also remember that kiss Katy give Niall and bandmate Harry Styles during the 2012 MTV Video Music Awards.

Back in Tokyo, Niall sent photos of himself alongside “my lovely wife” and “my groomsman” goofing around in the studio.

“Today was so fun at music station in Tokyo ! Had such a laugh with the lads and @katyperry ! Love that girl !,” Niall tweeted.

He wasn’t the only one with the maybe-someday Mrs. Niall Horan telling her fans, “Today could not be a better day! I get to hang with @pamyurin & @onedirection on MUSIC STATION in TOKYO!”

Guess John Mayer should have moved a little faster...
