In September,a source told PEOPLEthat the romance between Pratt and Schwarzenegger was heating up — and that the couple could get engaged quickly.

“They’re such a great fit together,” the source said at the time. “It’s only been a few months but Chris and Katherine are both very serious about the relationship and their friends wouldn’t be surprised if they got engaged sooner rather than later. Katherine has spent time with Chris’ family and they all love her too. She fits in really well with them and vice versa.”
