Married at First Sight couple Jamie Otis and husband Doug Hehner have revealed whether they are expecting a baby girl or boy.

Jamie and Doug, who tied the knot on Married at First Sight's first season, made the big announcement on their Married Life reality series in a gender-reveal special that aired Tuesday night, April 25 on FYI.

"It's a GIRL!... Our sweet rainbow baby. We are so thankful for this sweet, sweet baby GIRL rolling around happily inside me...Her big brother, Johnathan, has been watching over her and keeping her safe. We love them both more than words could ever express...#rainbowbaby #angelbaby," Otis, who found fame when she competed for Ben Flajnik's heart on The Bachelor's sixteenth season, captioned a photo of Doug and herself at the party.

In the photo, Jamie and Doug appear to be standing in their backyard. Jamie was wearing a bright pink dress while Doug was sporting a light blue dress shirt.

Jamie wrote on Instagram she's so thrilled to "shout it from the rooftops" that she's pregnant with "a precious baby girl."

Jamie, 30, and Doug, 33, first announced they have a baby on the way in February 2017.

The happy news came just six months after the reality TV stars revealed in July 2016 that Otis had miscarried the couple's first child, Johnathan Edward, when he was four months along into the pregnancy.

Jamie discovered she was pregnant again on December 20, 2016, which ironically just so happened to be Johnathan's due date.

"Get ready for all the Mommy & Me matching outfits and twinning! I  cannot contain my excitement - I was so shocked and I'm just SO, SO, SO happy!!! I could go on & on about how incredibly stunned/excited/blessed/thankful I am.... there are just no words to how I am feeling," Jamie continued on social media.

And Doug seems equally excited about the idea of welcoming a daughter into his life and being surrounded by girls. (The couple currently shares two female dogs as well).

"Im going to be a daddy to a baby GIRL!!!....I'm bracing myself for lots of tutus and bows! couldn't be HAPPIER!!!" Doug captioned a photo from the gender reveal party on his own Instagram account.

In an interview with People, Jamie disclosed she was "so shocked" to discover the sex of her child.

"I was pretty certain it was another boy. If you follow the old wives' tales, I had no symptoms of [having a] girl," the mom-to-be told the magazine.

"I've always wanted to have that mother-daughter relationship that I kind of missed out on with my mom. I secretly hoped to be a mommy to a little girl and to have a little mini me."

"I was thinking more about 'healthy' than I was 'boy' or 'girl,'" Doug shared with People. "I am still cautious and it was tough in the beginning to get excited. But as the weeks... pile on and I see the baby bump get bigger and bigger, I cannot stop smiling!"

Doug added that he's looking forward to that "unexplained special bond" men tend to have with their daughters -- a feeling he anticipates will be "amazing" when she is born.

The couple's little bundle of joy is reportedly expected to arrive on August 24, 2017.
