Sylvester Stallone has strong genes.

The 75-year-old "Rocky" actor is father to five children: Sage, who died of heart disease at 36 in 2012, Seargeoh, about 42, Sophia, 24, Sistine, 23, and Scarlet, 19.

He shares his three daughters with former model Jennifer Flavin. The trio was selected to serve as Golden Globe ambassadors in 2017.

On Wednesday, the proud father took to Instagram to share a photo of himself standing with his daughters.

For the photo, the actor kept his outfit simple, wearing a plain blue t-shirt and jeans while his daughters dressed it up a bit for the occasion.

Sistine, a model and actress, wore a silky green dress with a thin golden belt, Scarlet wore a black dress with light-colored decor and Sophia donned a leather-like cocktail dress with a matching black jacket. 

Each of the three daughters completed their outfits with jewelry and stood about as tall as their action star father.
