Chris Pratt and Katherine Schwarzenegger are planning a summer wedding

A source said: “They are one of those rare couples that you root for from the beginning. It won’t be a long engagement - Katherine has already talked about having a summer 2019 wedding.”

Chris, 39, and Katherine, 29, are also reportedly planning a “religious wedding”, as the pair bonded over their shared Christian faith when they started dating back in June last year.

The source added to People magazine: “They’re going to want a religious wedding. I know that Chris does, and I assume that she does, too. God is going to be a part of this marriage.”

The news comes after it was claimed earlier this week that the couple had already begun planning their big day.

A source said: “[They are] already starting to plan. They are thinking about Martha's Vineyard which is a special place for Katherine and where she spent a lot of time growing up. Chris wants her to have her perfect day and whatever she wants. It will be a big wedding and very traditional.

"They will have an engagement party and bridal shower for Katherine coming up. It’s a very special time for the family and everyone is completely thrilled. They can't stop smiling and celebrating.”

‘Jurassic World’ star Chris - who has six-year-old son Jack with ex-wife Anna Faris - shared the news of their engagement on social media over the weekend, with a picture of him and Katherine hugging, with her engagement ring on display.

Alongside the snap, he wrote: “Sweet Katherine, so happy you said yes! I'm thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!”

Katherine later reposted the photo to her own Instagram, adding: "My sweet love. Wouldn't want to live this life with anyone but you.”
