Alexa and Carlos PenaVega have revealed the sex of their upcoming baby.

On Sunday, Aug. 21, Alexa — who has appeared as Kiley Brenner on the NBC-turned-CMT series “Nashville” — shared a sonogram photo of the soon-to-be member of their family on Instagram. In the caption of her post, she revealed not only the sex, but also the unique name of their forthcoming little bundle of joy.

“Ocean King PenaVega. We can't wait to meet this little Blessing,” the 27-year-old actress wrote. “#BabyPenaVega #MyLilMan (Yes... That's his name for those who are confused)”

Carlos, also 27, shared the same pic on his own Instagram account with the caption: “OCEAN KING PENAVEGA #babypenavega #daddyslittleboy.”

Alexa revealed her pregnancy on Instagram in June. “I cannot believe I finally get to say this... WE'RE PREGNANT!!!”  she captioned a picture of her being kissed by Carlos on the cheek. “I t’s #ClearblueConfirmed that a little blessing is joining the PenaVega family!!! We can't wait!!! #ItsHappening #HolyWow #LosForDaddyOfTheYear #ClearbluePartner.”

Ever since the pregnancy announcement, the pair has been actively documenting their journey to parenthood on social media.

Just last week, as E! News noted, the husband and wife kicked off a babymoon vacation on Royal Caribbean’s Allure of the Seas cruise. 

Alexa and Carlos, who started dating in late 2012, got engaged in August 2013. Carlos popped the question while on a cruise with friends.

“We are like old people, so we like to [go on cruises] a lot. We were on a cruise … with 25 of our friends. He proposed the first night at dinner,” Alexa recalled during an interview with Access Hollywood in October 2013.

The couple then tied the knot in January 2014 at the Grand Velas Riviera Nayarit in Puerto Vallarta, Mexico.
