The "Varsity Blues" star showed off her baby bump in a whipped-cream-free bikini on Monday, posing for her husband Hayes MacArthur -- who posted the pic above.
"Bumpin'," he captioned the shot.
The "Legends" star, 38, revealed her second pregnancy on "The Tonight Show" earlier this month.
"It's such a scary time. I've been trying to hide it as much as I can and when you're in the public eye, it's very scary in the beginning," she told Jimmy Fallon. "I was still shooting my spy drama and I have to be a covert spy in my real life to, so I'm wearing blazers and push-up bras and everything you can do to distract from this bump that's growing."
This baby will be the couple's second. They're also proud parents to son Theodore, who turns 4 in December.
