Chris Pratt and Katherine Schwarzenegger's relationship has hit cruise control ... thanks to a couple of Birds.
Chris and Katherine jumped on a couple of those super popular Bird scooters Sunday in Brentwood on their way to a family dinner at Mom Maria Shriver's pad. Chris seemed serious at first, but eventually cracked a huge grin. Birds are fun.
As we reported ... Chris' kid, Jack, has been warming up to his dad's new GF. The trio looked like a picture-perfect fam bam out together last week in Malibu.
It's obvious both families are on board with this couple. It's just how they roll.
