Dwayne “The Rock” Johnson may be the Sexiest Man Alive, a legendary WWE star and one of today’s hottest actors (how cute was Moana?!), but he’s one huge adorkable softie when it comes to his duties as a dad.

Need proof? Dwayne’s youngest daughter, Jasmine, turned one this week (the 44-year-old is also a proud dad to 15-year-old daughter Simone from a previous marriage), and the beaming papa celebrated by serenading his little girl with a sweet rendition of “Happy Birthday.” Taping the candid moment to share with his followers on Instagram, Dwayne revealed a seriously impressive (and surprisingly soft) singing voice, as Jasmine showed her support by clapping along.

“Teaching ’em young to start applauding the moment daddy starts singing,” he captioned the clip. “Smart girl. Answering my egotistical questions is clearly a work in progress ;). Happy 1st Birthday baby girl. Got you for life. #Aiga#PuaMana.”

Okay, can we just take a second to swoon over Jasmine’s beautiful blue eyes? She is too. cute. for. words!

In the video, Dwayne can also be heard proudly declaring, “She’s already clapping!” then asking his little munchkin, “Who’s the best daddy in the world?” Although she doesn’t quite give the response he was hoping for, with a voice like that, it’s defs safe to say you’re up there, Dwayne!
