Sarah Wright is pregnant — again!

The 32-year-old actress and her NCIS: Los Angeles actor husband, Eric Christian Olsen, 38, announced they are expecting their second baby via Instagram on Saturday, Feb. 27. The couple are already parents to a two-year-old son, Wyatt Oliver, whom they adorably call "Little Bear."

"Deep talks with #LittleBear and our new #LittleLove due this summer. #Surprise #Baby #When3Becomes4," Sarah captioned a sweet photo of herself and Wyatt on the photo-sharing site.

"This picture is either one of two things: Wyatt fully embracing and loving his impending new baby sibling. Or he is trying to push them both down a steep embankment, in a last ditch effort to preserve sole ownership of his train set," Eric jokingly captioned the same photo of his wife and son on his Instagram account.

Eric and Sarah — who most recently starred on the NBC sitcom Marry Me — first began dating in 2007 and later married in June 2012. They welcomed son Wyatt in August 2013.

Congrats to the couple on their second pregnancy!
