"What a surprise! I feel the luv. Now let's go DESTROY all this sugar and carbs," Johnson wrote alongside a video of his on-set party. "I get called to set on #RAMPAGE and our entire crew surprised me to sing happy birthday.
Cooked up all my favorite cheat foods - pancakes, s'mores and pizza."
"Any movie I star in/help produce, we always try to create the best work environment for our crew. Assemble the most talented in the business and make it feel like one big family. This hard working, brilliant crew is just that.. the best in the business and family," he continued. "Thank you crew so very much for this effort and surprise. I'm one very grateful big, brown, bald, tattooed SOB."
"Luv you guys, lets get back to work, make a great movie and whoever ate all my s'mores is a real 18 karat a**hole. Kidding that was me," he concluded. "#OnSet #BirthdayLuv #OurCrew #RAMPAGE."
On Thursday, Johnson's "lovely ladies" surprised him by decorating his trailer.
"Birthday luv. On set shooting #Rampage, between scenes I come back to my trailer to get a lil' work done and my lovely ladies surprised me by decorating my entire trailer - including a little blue fuzzy birthday hat left on my desk, but my head's too damn big to wear it," he captioned a shot of his epic trailer. "To the left you'll also see a Pikachu birthday balloon and on the table, two of my fav bottles of tequila."
"C'mon Pika, big daddy doesn't drink alone, so you set em up and I'll knock em down," he added. "#OnSet #DJsTrailer #BirthdayLuv #PikaGetsHammered."
