"The first #MarriedAtFirst baby is here!" a tweet from the Lifetime series' account read. "Congrats @jamienotis and @DougHehner!"

According to People, daughter Henley Grace was born at 5:24 a.m. in New Jersey, weighing in at 8 lbs., 2 oz.

"I've never been more in love," Otis later wrote on Instagram. "@henleygracehehner, you're mommy's everything."

And it looks like Henley already has her own Instagram account (run by her parents, of course). Her latest snap features her all bundled up in Hehner's arms.

"Wrapped around my daddy's finger already," the caption reads. "#skintoskin #daddysgirl #newborn."

Congrats to the happy couple!
