The Rock's baby daughter slaps his head like a drum in heart-warming video

Dwayne 'The Rock' Johnson turns into a ball of mush around his eight-month-old daughter Jasmine. Case in point: The action star let her use his head as her own personal bongo drum in a new Instagram video.

"Finally my big head is used for more than just a place to hang my hat," the 44-year-old captioned the clip. "The joys of being home w/ my ohana and playin' one of our fav games - slap daddy's head 'til I can see his big scary face."

The Central Intelligence star, who is half-Samoan, made special mention of the video's meaningful music.

"Song playing in the background is 'O Tiare' (Justin Young)," he wrote. "A song I started singing to her every day since she was one week old. Samoan lyrics are beautiful, 'Ia alofa le Atua, ma tausi ia te 'oe...' which translates to 'may God take loving care of you'."

The Rock welcomed Jasmine with his long-time girlfriend Lauren Hashian last December, and he is also dad to Simone, 14, from a previous relationship.

"I was right there during labor," he posted after Jasmine's birth. "Helping her breathe, every highly intense contraction, every second of pain, right there watching the actual birth, cutting the cord and wiping the tears."

The WWE wrestler clearly has no problem being a hands-on dad, but he made sure to assure his fans he's still got a sliver of a tough side left.

Along with a #SlapDaddysHeadCauseItsABigToy hashtag, he concluded, "I must now go do something very manly and bad ass to counterbalance this post."
