It's no secret that One Direction's Niall Horan has a growing crush on Katy Perry and now he's taken things to the next level.
Earlier this week, he publicly appealed to the I Kissed A Girl singer to marry him on Twitter.
And now that he's come face to face once again with his idol, he has taken it one step further.
"She said yes! It's happening! Haha," he wrote with a photo of the two of them posing together on Instagram.
Perry told X Factor viewers last weekend that she was happy to put the "cute" Mullingar singer through on the talent show in 2010 when he auditioned and she was filling a role as a guest judge.
It was in boot-camp that Niall, Harry, Louis, Zayn and Liam were joined together to form a band.
The One Direction singer is currently touring Australia with his four band-mates.
The boys have admitted they’ve been trapped in their hotel rooms for most of their trip Down Under so far as their level of fame is so intense in Oz.
The two are old pals, with Perry famously giving Horan a friendly kiss at last year's VMAs on stage.
