There's no job Dwayne "The Rock" Johnson takes more seriously than being a dad.

The actor shared a photo of himself with his two youngest daughters, Jasmine and Tiana, on Instagram, along with a sweet promise to the girls. The Rock, 46, promised to "love and protect" his daughters as long as he lives, noting that he's taking advantage of every opportunity to hold the girls in his arms while he's still able to.

"Daddy's arms. I ain't gonna be able to hold 'em like this forever, so you better believe I snatch these cookies and love 'em up every moment I can," he wrote. "Plus, I know there's gonna come a day where in daddy's arms is the last place they want to be. Baby Tiana Gia is already there with the 'help me' look on her face."

He continued, "Can't guarantee I'll love and protect my daughters for the rest of their lives, but I can guarantee I will for the rest of mine."

The Rock has always been candid with fans about fatherhood. In July the former professional wrestler was asked about his youngest daughter, Tiana's, cutest moments.

"The cutest thing is when I hold her and then she throws up on me and cute things like that," he joked to ET Online. "Poos, beautiful!"

In addition to his two young daughters, The Rock has a 17-year-old daughter named Simone.
