Schwarzenegger shared the same sweet snap, writing, "My sweet love. Wouldn’t want to live this life with anyone but you."

The “Avengers” star began dating Schwarzenegger earlier last year. Pratt finalized his divorce from ex-wife actress Anna Faris in October 2018. They were married for nine years and share 6-year-old son, Jack.

Pratt was rumored to be dating Schwarzenegger since June of 2018, following his high-profile divorce. However, despite all the rumors and public outings, they only made their relationship official to the public in mid-December. The "Guardians of the Galaxy" star posted a collage of photos of Katherine along with a sweet caption celebrating her 29th birthday.

"Happy Birthday Chief! Your smile lights up the room. I’ve cherished our time together. Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care," he wrote.

Schwarzenegger's mom, Maria Shriver, congratulated the couple on Monday writing on Pratt's Instagram post: "Congratulations to two loving kind caring thoughtful Spirtual people we are so happy for you you are blessed as is everyone who knows you yes let’s go."

Last week, Pratt's ex-wife opened up about the end of their marriage and what it's like to be co-parents to their son now that they've both moved on with different people.

“Chris and I work really hard ‘cause we have Jack, that is sort of the long game idea and making sure Jack is really happy, which makes us really happy,” Faris says on her “Unqualified” podcast. “We have sort of the luxury of circumstance. You know, we are both in other loving relationships. … But It’s like, how do you not in general sink into a place of bitterness?”
