Dwayne Johnson is wishing his mother Ata Johnson a happy birthday!

On Wednesday, Johnson, 51, shared a video to Instagram of himself singing with his mother Ata, who turns 75 today. Ata can be seen playing a ukelele in the video as she and Dwayne performed a special birthday song together.

“Don’t start crying,” Dwayne jokes in the video, before his mother says: “I want to sing. Do you know how to sing in tune?”

“I know how to sing in keys that don’t exist,” Dwayne joked, before launching into the tune. During the song, the pair joked that Ata is only turning 59 before Dwayne placed a pink-colored lei around her neck and planted a kiss on her head.

“Before I even start singing to my mom her special Happy Birthday song, she starts to cry 🥹,” Dwayne wrote in an caption to his post. “Probably because I always sing in keys that don’t exist 🤣 🎶🙋🏽‍♂️”

“HAPPY BIRTHDAY MOM!!!” he added in the caption. “75 years of experience, wisdom, hard times, good times, laughter, mana, and yet thru it all — you TRULY have the KINDEST HEART I have ever known ❤️💫 I feel like the luckiest son on earth.”

To top the post off, Dwayne wrote “Ou Te Alofa Ia Te Oe 🌺,” which roughly translates from Samoan to English as “I love you.”

Dwayne’s happy birthday post to his mother comes nearly nine months after he shared with his fans that Ata was involved in a serious car crash in February. The actor said days after the incident that his mother was “doing good” and that he was alerted of the accident via a phone call in the middle of the night.

“Angels of mercy watched over my mom as she was in a car crash late last night. She’ll survive and continue to get evaluated,” Dwayne wrote of the incident in a Feb. 2 Instagram post. “This woman has survived lung cancer, tough marriage, head on collision with a drunk driver. She’s a survivor, in ways that make angels and miracles real.

Back in May, Dwayne shared an Instagram video of himself and Ata slow dancing together as a band played Louis Armstrong’s “What a Wonderful World” to celebrate Mother’s Day.

“I always say, if we got a good, loving mom, then we got a shot at growing up to become a decent human being,” he wrote in a caption at the time. “I got lucky, my mom is one of the good ones.”

Dwayne’s father, professional wrestler Rocky Johnson, died of a pulmonary embolism in 2020 at age 75.
