Chris Pratt’s wife Katherine Schwarzenegger holds hands with actor’s seven-year-old son Jack in LA

She turned 30 earlier this month.

And on Sunday, Katherine Schwarzenegger was in full stepmom mode as she spent time with husband Chris Pratt’s seven-year-old son Jack.

The two, who are both celebrity offspring, were seen enjoying a walk together in LA before stopping to pick up some juice to go.

Jack is 40-year-old Pratt’s son from his marriage to actress Anna Faris, 43, which ended in divorce in 2018.

The Guardians of the Galaxy star tied the knot with the daughter of Arnold Schwarzenegger and Maria Shriver in June, one year after going public with their romance.

Jack was dressed in a Spiderman hoodie and navy sweatpants with blue Velcro sneakers and held hands with his stepmom as they walked along.

Katherine wore a long-sleeve athletic top and black leggings with a plaid shirt knotted around her waist.

She had a baseball cap pulled down over her hair and sported large black-framed sunglasses.

Pratt has been busy of late pulling double duty as star and executive producer of the sci-fi action movie The Tomorrow War.

The film is currently shooting in Atlanta, Georgia. 

Originally called Ghost Draft, The Tomorrow War is about people recruited from the past to fight a future war against alien invaders.

Pratt stars as one of these soldiers and it turns out that the fate of humanity relies on his ability to confront and correct his past.

The actor is also fronting a series of promotions for retail giant Amazon in which he showcases a range of workout and fitness products available via the Amazon website.
