Dave Annable had someone special to celebrate on Sunday: his wife!

The former Brothers & Sisters and Red Band Society star and Odette Annable are expecting their first child, they both announced on social media.

“Happy Mother’s Day! This year, I’m SO happy to announce that I got to join the party!” she Tweeted along with a photo of the parents-to-be.

The actor made sure the Banshee actress, who will next star in The Astronaut Wives Club, was showered with plenty of love — as her first Mother’s Day wasn’t the only thing the couple were celebrating.

“It’s out! I can now wish my beautiful wife a very happy birthday AND a happy 1st #MothersDay!” he wrote. “Me and #babyannable are so lucky to have you.”

Dave, 35, and Odette, 30, have been traveling overseas and sharing photos of their vacation along the way. But their stop in Paris could be their cutest yet.

“The other half of our Europe trip. It has begun. @OdetteAnnable in her element,” he captioned a photo of the expectant mama shopping for baby.

The pregnancy is no surprise: Before the pair tied the knot in October 2010, Dave told PEOPLE he was looking forward to starting a family.

“I want a little hockey team,” he said. “I’m a little bit older than she is … I’m going gray, I wear cardigans now. It’s time … I have the itch.”

I was a huge fan of Brothers & Sisters but I don’t remember him….

he was the youngest brother Justin…the one with the drug problem.

Every time I’m reminded of that show, I realize how much I still miss it.

Best show ever!

Thanks DaisyMoon!!! Remember the character well but man, the years have taken a toll — relative to everyone else (Calista, Sally, Patricia, etc.) he has really aged.

No problem!

(Yeah…with all that gray hair he definitely looks older than 35!)
