Pratt took to IG on Saturday morning and showed off his extremely impressive, and extremely red, sunburn that covers his entire back.
The "Avengers: Endgame" star wrote, "Suns out guns out I might have got a toouuuch crispy on the honeymoon."
He also made sure to include a cheeky peek of his booty, to show the contrast in skin tone.
At least Arnold Schwarzenegger can rest easy knowing his daughter and her new husband weren't skinny dipping on their honeymoon!
Some celebrities are already offering up advice for Pratt, who hashtagged his IG post, "#aloe."
Gwyneth Paltrow, who regularly posts great comments online, told Pratt, "I've got some goop for that."
Pratt's wife also got in on the fun, but just posted fire emojis.
After recently tying the knot, Pratt and Schwarzenegger took off to Lenai and honeymooned at a luxury island resort.
Before taking off to Hawaii, the two stars celebrated Father's Day with Pratt's 6-year-old son, Jack.
Schwarzenegger also paid tribute to, not only her own father, but her new husband on Father's Day in a touching social media post.
"Watching you be such a hands on and loving father was one of the many reasons I fell in love with you, and continue to each day," she wrote.
It's possible more children are in the future for the happy newlyweds, as Pratt has regularly spoke on wanting a larger family.
For now, Schwarzenegger is already a mama to her beloved rescue dog, Maverick.
The first thing she did after getting home from their honeymoon was post a photo with her furry friend ... and of course pop a bottle of wine.
Schwarzenegger loves her dog so much that he is also her co-author on her children's book about adopting the pet, "Maverick and Me."
Hopefully, Maverick is gentle with sunburns.
