The Rampage star took to Instagram on Monday to share a heartwarming photo of his ladylove lying in bed with their daughters -- 3-week-old Tiana and 2-year-old Jasmine -- as they watched a movie on their laptop.
"Happy Mother’s Day to my main squeeze @laurenhashianofficial, holding my little main squeeze, Jasmine Lia, who’s holding my tiniest main squeeze, Tiana Gia," Johnson, 46, captioned the pic.
"I’m in constant respect and grateful awe of all the things this incredible mama accomplishes on a daily basis," he continued. "Here’s a fun small recap: Having a two and half year old and a newborn attached and clinging to her 24/7. Managing the wonderfully fun, Terrible 2’s with Jazzy. The 'Hi, I need to eat every 3hrs and preferably from your boob'… with Baby Tia. Managing multiple family properties. Managing an ever growing staff of family employees across the country. Picking up the ENTIRE FAMILY, STAFF AND DOG and moving to multiple locations AROUND THE WORLD, throughout the year because of my filming and production schedule. All while continuing to build an amazing career as a music and song writer/producer."
"And here’s the best part and the thing I’m most proud of… Lauren does it all with a big genuine smile and is truly, the kindest and sweetest soul you’ll ever meet," he added.
Johnson also marveled at his good fortune, sharing, "Of all the human beings on this earth she could have as her partner -- she chose me. One big, brown, bald, tattooed, very lucky SOB."
"Happy Mama’s Day Lauren," he concluded. "Take a bow and Queen it up - you’re an amazing mama and amazing mama’s make this world go around."
Johnson -- who is also the father to 16-year-old daughter Simone Alexandra, from a previous marriage to Dany Garcia -- welcomed baby Tiana on April 17.
ET caught up with Johnson weeks before his baby girl was born, and he said he was worried that she might arrive in the middle of his promotional schedule for Rampage. Although he had an "emergency plan" in place in case that happened.
"We have plan B's all set. I'm ready to pivot at any time," he said. "I'm ready to come back, believe me. The pilot is already ready to turn that plane around if things start to happen."
