The "Terminator" is 72! Arnold Schwarzenegger's Kids Publicly Honor Him By Sharing Splendid Family Photos

Date July 31, 2019

On Tuesday, Arnold Schwarzenegger celebrated his 72nd birthday, and several of his children took to social media to publicly honor their dad.

Joseph Baena, Arnold's 21-year-old son he fathered with the family's housekeeper, got the birthday tributes started, sharing an image of the father-son duo, both in outstanding shape, working out together at Gold's Gym. Schwarzenegger points to his son with pride as he gets in an arm workout.

"BIG happy birthday to the best training partner in the world! Love you dad,"

- Joseph captioned the snap of the fitness fanatics at Gold's Gym

A few hours later, Patrick Schwarzenegger, 25, posted a photo with three of his siblings and their dad.

In the image, the actor holds up a candle-speckled cake with his picture on it. In the cake image, Arnold smokes a cigar in a hot tub.

"The cake, Happy Birthday big guy."

- Patrick wrote with two laugh-crying emojis.

Arnold Schwarzenegger has five children but the four children he shares with his ex Maria Shriver — Katherine, 29, Christina, 28, Patrick, 25, and Christopher, 21 — aren't necessarily close with Joseph, who Arnold acknowledged as his son in 2011.

Unfortunately, both Arnold's daughters Katherine and Christina "have really no relationship with Joseph. I think the sons have more of a relationship with him," a source told Page Six.

Even though the famous star's children might not have very close relationships, we do hope they all reunite at least for their father's birthday!
