"Ahhh!!! Happy birthday honey!! You always make me laugh. And I love being romantic over twitter. @prattprattpratt," Faris wrote in response to a fan's funny pic of the couple at the Guardians of the Galaxy Vol. 2 premiere earlier this year.
ET caught up with the pair at the GOTG2 premiere in April, where Faris couldn't help but gush about her hubby.
"I'm in awe," she said. "On the way here, I was so much more nervous than Chris was… I felt like I've always known he's a brilliant actor. And now I feel like the rest of the world is getting to see that. I'm so thrilled about this movie."
