Pratt, 39, posted a photo of his 29-year-old bride-to-be cuddling with a lamb on Saturday, writing, "@katherineschwarzenegger rocks the latest trend in fierce accessories. The eggshell wool baby lamb. Super high maintenance but worth it for this fashion icon. #farmlife."
On Valentine's Day, the "Guardians of the Galaxy" star showed off his season's first lamb, which he named Cupid in honor of the holiday.
Pratt is an avid lover of farming, much to the chagrin of critics who consider his farm-to-table and hunting habits "problematic."
The actor previously revealed that he's looking forward to spending more time on his farm and less time on movie sets, telling press that in the future he wants "lots of kids."
"Maybe less time spent working, more time spent enjoying life," he said. "I always want to be that guy that works to live, not lives to work. I think [I want to spend] just a lot of time at the farm and a lot of time catching a lot of fish and seeing lots of sunsets."
