He explained that the image was a reflection of their relationship. \"As you go out and tackle this big ol’ world with your dreams, ambitions and hard work, the love you’re able to see daily will always guide you,\" he wrote. \"It’s your strength.\"

\"But remember it’s ALSO the love you never see thats quietly guiding and boundlessly supporting you every step of your journey’s way,\" he continued. \"From us loved ones who are still here, to your loved ones who aren’t. That love is your MANA. Your spirit, your soul.\"

The Rock also declared a \"big tequila toast to my #1 (who does NOT drink so her father will drink for the both of us 🥃🤣)\" in the post.

Dany Garcia, Simone's mother and Johnson's ex-wife, also shared a photo with her daughter to celebrate the big day. \"18 came so fast my brilliant beautiful daughter,\" she wrote. \"@simonegjohnson you are a GIFT.\"
