Lili Reinhart is 22 years old! To celebrate, Cole Sprouse posted a snap of his girl on Instagram with the most adorable birthday message: "Both the birthday and the gift. My little muse, happy birthday my love."

While that sentiment had us swooning over Bughead, it's actually the accompanying photo that had our jaws on the floor.

Are you sitting down? Good. Because this topless photo of Reinhart will surely sweep you off your feet. She's standing in front of a mirror wearing nothing but black bottoms, with her arms covering her chest.

Both the birthday and the gift. My little muse, happy birthday my love.

Like are you kidding me with this, Cole? Are you trying to kill us?

I'll be honest: I'm having some major flashbacks to Betty Cooper's Southside Serpents initiation on "Riverdale." I mean...

Anyways, last month Reinhart shared an equally adorable message, minus the racy photo, to celebrate Sprouse's birthday.

"It seems as if the world would still be a stranger to me, if not for you," she wrote. "I'm so thankful that our paths intertwined to form this beautiful adventure~ Happy birthday, my love." Yes, they both called each other "my love," and we're not crying, you are!

Not only are these two capturing hearts as Bughead on the CW's "Riverdale," but they also have fans losing their minds IRL as well.

6am.

Despite the fact they refuse to actually discuss their relationship in public.

Sprouse, who moonlights as a photographer, has been taking photos of Reinhart all over the world since they started dating.

And they are truly some of the most beautiful snaps we've ever seen.

It's easy to see why fans can't keep their cool when it comes to this duo.

It’s pretty, pretty late

Not only over the recent birthday message...

But over literally anything these two do.

Happy birthday, Lili! Here's to another year of epic Instagram photo shoots and swooning fans.

Perhaps this will be the year these two finally declare their love in public.

A girl can dream, right?
