It looks like Chris Pratt has been indulging in Katherine Schwarzenegger Pratt's pregnancy cravings too!

On Thursday, the Jurassic World star, 40, shared that he's "gained a little weight" since social distancing with his pregnant wife, 30, amid the ongoing coronavirus pandemic, joking to Extra, "It's been tough."

"Pickles and ice cream. I never thought I would like 'em so much," he mused.

The actor went on to discuss how he has been handling Schwarzenegger Pratt's pregnancy, candidly telling host Billy Bush, "Can I be honest with you? I found myself complaining the other day about a little bit of low back and hip pain and how I’ve gained a little weight in quarantine… and she just looked at me sweetly."

He quipped, "I was like… ‘Oh, right, right, I don't really get to complain about that to you right now, do I?’ ”

Jokes aside, a source previously told PEOPLE that Pratt has been nothing short of a "dream husband" to the Gift of Forgiveness author throughout her pregnancy.

"Katherine is doing well, and Chris has been taking care of her," the source said. "Katherine still calls him her dream husband. They are very happy together."

"Chris has been doting on Katherine, and the pregnancy has brought them even closer," a friend of the couple added.

The couple, who will celebrate their first wedding anniversary in June, are expecting their first child together. Pratt is also dad to 7½-year-old son Jack, whom he shares with ex-wife Anna Faris.
