You know how some couples look so much alike that they could pass for brother and sister? (There’s an entire mildly disturbing Instagram account called @siblingsordating that’s dedicated to that exact concept.) Well, I’m not saying Millie Bobby Brown looks all that much like her fiancé, Jake Bongiovi, but they do suddenly resemble each other, at least from the hairline up.

Brown posted a super-cute mirror selfie of herself with her betrothed on Friday, August 4 — exactly the kind of photo you might expect from a couple that’s young and in love. Brown is wearing a drapey, yellow dress, a pendant, hoop earrings, and the chic, skinny highlights she’s been sporting for a few months. Bongiovi, on the other hand, is wearing a white, button-down shirt, a necklace and — quite frankly — the same damn highlights as Brown.

OK, so he doesn’t have the exact same face-framing money pieces that Brown does, but his hair — a similar medium-brown base shade as hers — is sprinkled with lots of anything-but-chunky highlights in a similar blonde hue. Because nothing says “goin’ to the chapel” quite like matchy-matchy balayage.
