As you probably know, this is Matthew Lewis, who played Neville Longbottom in the Harry Potter films and was the inspiration behind the phrase Longbottoming (read: when an adorable child actor grows into a beautiful swan).
And this is adorable child actor Millie Bobby Brown, who captured all of our hearts this summer as Eleven in Netflix's Stranger Things.
Well, they hung out together this weekend. And it looks like they had so much fun and WE WANT TO JOIN IN.
Matt revealed that he loved Millie's character so much, he even got a tattoo in her honour.
I'm pretty sure they just met at a convention, but my imagination is running away with me and now I want Matt to cameo in season 2 of Stranger Things.
Either way, this is DEFINITELY a friendship we want to be a part of. ❤️
