"Sweet Katherine, so happy you said yes! I'm thrilled to be marrying you. Proud to live boldly in faith with you," he wrote alongside a photo of the two embracing one another. "Here we go!"

RadarOnline.com readers know Pratt was first seen with Schwarzenegger in June of 2018, almost one year after announcing his separation from wife-of-nine-years Anna Faris.
While they kept their romance low-key at first, things quickly started heating up for the couple. Not only did Pratt meet his gal's family, but he also quickly integrated Schwarzenegger into his. The beauty was seen on several outing with the actor's 6-year-old son, Jack, and even spent Halloween with him and Pratt, as well as with Faris, 42, and her producer boyfriend, Michael Barrett.
This Friday, Pratt helped Schwarzenegger move from her Santa Monica home into his own mansion. And now, the two are getting ready to tie the knot!
