What a random pairing.

Harry Potter actor Mathew Lewis shared an image of himself hanging out with Millie Bobbi Brown which sent fans of the two into a bit of a meltdown in the comments section. If it wasn't random enough that the two are apparently friends, the tattoo on Mathew Lewis' arm caused even more confusion. Mathew shared a post of the two on Instagram on Sunday night and in it, he held up his tattooed arm. https://www.instagram.com/p/BLo5cIejZJG/?taken-by=mattdavelewis He captioned the post:  ''A lot of people ask what my tattoo means. Now you know.'' His tattoo is the roman numerals XI, which is 11. And since Millie's character in Stranger Things is named Eleven it's obviously a reference to the show. Now don't worry, he's not a super stalker, he's actually had the tattoo for a few years now, so he was obviously just having fun. Either way, fans were very confused about the whole situation and the meaning on the tattoo.

"I dont get it ?" One Instagram user said. ''Still don't understand'' said another. ''Can somebody explain that to me?'' asked another commenter.

Maybe they are just good friends, or maybe they are working on something together. Only time will tell.
