The 37-year-old actress says that Thicke is the one who sometimes gets jealous of her risqué movie scenes (like the ones she has in her upcoming flick Baggage Claim).
"I always prep him for the sexy scenes," Patton tells the Huffington Post. "I mean the moment he's not a little jealous is the day that I'm very worried, OK? And I think he feels the same way. You have to have a little bit of jealousy. But mostly it's happiness for each other because we've known each other since we were kids and we dreamt the same dream together and we know how hard it's been."
"It's had its peaks and its valleys," she continued. "It's a marathon. So when you have great moments like this, or when you just get to work, quite frankly, you're just so thankful that you can kind of overlook the things that might hurt a little bit."
Overall, Patton says she and Thicke are just celebrating the success of their respective movie and music careers.
"We celebrate in the kitchen late at night after we put our son to sleep," she gushed, adding, "And we're like, 'Can you believe this?' And then we do things like [tell each other] 'drive the speed limit,' 'don't mess around.' It's like 'don't mess this up!'"
