Dwayne "The Rock" Johnson is known for his movies, enviable style, and of course, his workout routine. Now, the actor and WWE star is showing off his paternal side.

Johnson shared a heartwarming photo on Instagram of his girlfriend Lauren Hashian and their newborn daughter Tiana. In the picture, Johnson is feeding Hashian while she breastfeeds Tiana.

Johnson captioned the photo, "I’ll handle this business. Mama has her hands full nursing/feeding Baby Tia, so I’m feedin’ mama her dinner. My pleasure," he said. "So much respect to her and all mamas out there holding it down and running things. Just landed and good to get all my girl’s settled in. Now, I gotta go satisfy my own appetite. Iron Paradise, here I come."

As for the Iron Paradise that Johnson references? That's what the actor calls his gym. The "traveling carnival" goes with him wherever he shoots his movies, and it contains over 40,000 pounds of steel and iron workout equipment.

Johnson is also father to daughter Simone, 16, with his ex-wife Dany Garcia, and shares two-year-old Jasmine with Hashian. He posted another sweet family photo this past Mother's Day, calling Hashian "a brilliant visionary storyteller and lyrically gifted—all qualities that are hard to tap into when you’re managing this nonstop life of ours. But she does it like a brilliant bad ass. "
