The Annables are adding to their incredibly attractive family!
Odette Annable took to Instagram on Sunday to share some very special Mother's Day news -- she's expecting her first child with hubby Dave Annable.
"It's a very special Mother's Day indeed. Wishing all the moms out there a very happy Mother's Day," the "Banshee" star captioned the post. "This year... I'm SO happy to announce that I get to join the party! #babyannable my bestie @hellobluephoto."
In the photo, Odette has her hand around her growing baby bump while the "Brothers and Sisters" star gazes down at his wife with a giant smile on his face.
Dave also shared his excitement via Twitter. "It's out! I can now wish my beautiful wife a very happy birthday AND a Happy 1st #MothersDay! Me and #babyannable are so lucky to have you,"he posted on Sunday.
The cute couple -- who tied the knot in 2010 -- are currently vacationing in Europe and they've already started shopping for their family addition!
"The other half of our Europe trip. It has begun. @OdetteAnnable in her element. #imintrouble #babyannable," Dave captioned a shot of Odette holding a tiny souvenir.
