The birthday girl and her husband, 41, were later seen stepping out on Sunday for a family walk alongside mom Maria Shriver, brother Patrick Schwarzenegger and his model girlfriend Abby Champion.

Opting for comfort on her special day Katherine wore a cozy brown tracksuit and a white sherpa jacket. 

She rocked a pair of white sneakers and left her stylishly chopped hair down throwing half of it up into a top knot. 

Sunglasses on her face and a black face mask for safety, she walked arm and arm with the Guardians Of The Galaxy star while clasping her phone in hand.  

Pratt sported all black for the athletic outing as he rolled his pants below his knees and threw on matching Adidas and a baseball cap.

Pratt wore a long sleeve black shirt that had a cross on the left breast as he made no secret about his devout faith. 

He put his arm around the author as they talked closely while trailing a bit behind the rest of her family as she fielded some birthday messages. 

Shriver was suited up in black leggings and a baseball cap, while Patrick put on a quirkier display for the walk in jeans and a white crew neck with a panama hat.

Not present for the celebratory outing was sister Christina, 29, and brother Christopher, 23 or the couple’s newborn daughter Lyla who appeared to be safely at home.

Katherine’s father Arnold Schwarzenegger paid tribute to her earlier in the day as he called her a ‘bright light in [his] world,’ while commending her on her writing and motherly accomplishments.

Pratt penned a lengthy post for his bride accompanied by a photo collage of them throughout the years as he wrote: 

‘Happy Birthday Sweetie! You have brought so much light into my life. I’m so glad to be home with you and Lyla.’

He continued, ‘You’re a great mom, a great step-mom, a great wife, daughter, sister and friend. The world is brighter with you in it. I am one lucky man. Thank you for the love, support and partnership. I love you.’

The photos offered a small glimpse at their four-month-old daughter, though Pratt cleverly covered her face with a Santa sticker as the couple continues to protect her privacy. 

The pair first got together in 2018 after meeting at church and were swiftly engaged a little over six months later. 

They moved in together and tied the knot in the summer of 2019 before starting their family together in the spring of 2020.
