The 'Avengers: Infinity War' star beamed as they left a worship service in LA together.
The 39-year-old leading man wore jeans and a black shirt for their morning together in LA. Meanwhile, Schwarzenegger sported a flowing striped dress with a plunging neckline under a denim jacket. She also wore her blonde locks in a loose bun for their outing.
After the service, Pratt and Schwarzenegger were seen socializing with friends before climbing into his silver Tesla and driving off. This new photo arrives just as ET has received new reporting that suggests the two have really bonded. So much so, Schwarzenegger has been doing activities with just Jack, Pratt's five-year-old son with Anna Faris.
"Chris Pratt and Katherine Schwarzenegger are the real deal," a source tells ET. In fact, Schwarzenegger and Jack were spotted solo at The Grove recently.
“Chris and Katherine are a serious couple so Jack being alone with Katherine is normal,” the source says. “Anna and Chris are great co-parents and respect that each other are in serious relationships. Jack will be spending quality time with each other’s partners.”
After leaving church, the couple joined Schwarzenegger's family for dinner. We know this because her brother, Patrick Schwarzenegger, shared an Instagram Story in which she and the movie star are seated at the end of the table together.
Last week, Pratt and Schwarzenegger made the same trip to church together, except that time Jack tagged along. Afterward, the trio all got ice cream together. That's where the Pratt and the 28-year-old daughter of actor/politician Arnold Schwarzenegger shared a passionate kiss.
"[They] went from casually dating to spending much more time together," a source previously told ET, adding that they've "gotten serious, quickly... Chris and Katherine have introduced one another to their family and friends, and have been almost inseparable when they are free."
"That was a big step for Chris," the source added. "Until he knew it was more than just casual, he wasn't introducing Jack to anyone. Chris and Katherine are very happy together."
Relationship rumors concerning the pair first started circulating in June when they were seen enjoying a casual picnic together in Santa Barbara, California. It's Pratt's first relationship showing promise since he and Faris got divorced in December of 2017.
