Harry Styles is a rather popular guy of the moment, His first solo album dropped exactly a week ago and he's spending the last few days making appearances on The Late Late Show With James Corden. While hanging out with his bud James, he of course had to join the host on the way to work for a Carpool Karaoke session and while you've probably been watching it on repeat just like we have, there seems to be another mega superstar who is major Hazza fan too: the one and only Justin Bieber.

That's right, Justin is a total Harry. The Biebs took to his Instagram account to share a screenshot of his computer, where he was watching Harry and James' latest jam session.

"Just watched Harry styles carpool karaoke!! Hilarious! Also congrats on the album, it sounds great !" he wrote in the caption.

Woah, who knew Justin was such a fan? He did hang out with Harry's One Direction bandmate Niall Horan quite a few times, and the duo even famously made a meal together.

So who knows, maybe Justin has been a secret 1D fan all along. This Instagram post might just be the start of a beautiful friendship between these two and just imagine if harry and Justin were to ever team up for a duet of some sorts. Nope, don't think the world could handle it, tbh.
