Over the weekend, Sophie Reynolds celebrated a major milestone: the Disney Channel actress has officially turned 18 years old, making her a legal adult – a fact she can barely process herself! To commemorate such a big occasion in her life, many of her friends gathered to celebrate with cake and a fun party – and share their well wishes with the starlet.

But Sophie's good friend and Gamer's Guide To Pretty Much Everything co-star Cameron Boyce literally melted our hearts with the special tribute message he shared for her on his Instagram after attending her birthday festivities.

"Soph. My sister. Happy birthday. We share a love that people have trouble comprehending, that's how special it is," Cam posted along with a photo of the two of them hanging out on some waterside rocks together. "I'd be in a very different place without you… but just because you're an 'adult' doesn't mean you get to boss me around any more than you already do ? love you."

Are you sobbing yet, or what?

Cameron and Sophie have both previously squashed dating rumors, and even though fans definitely ship them together, this message really shows how special their friendship is. (And we wonder if she has a similar tear-jerker of a message in mind for Cameron's own 18th birthday, which is coming up next month in May.)

"Thankful for friends who make me feel like a kid even tho I'm an 'adult' now. Thanks for all the bday wishes guys," Sophie added on her own Instagram after her party. It looks like she had a wonderful celebration, surrounded by her most supportive BFFs!
