It's been a whirlwind of a year for reality stars Ethan and Amber Diamond (formerly Amber Lee). The couple met in Hawaii last year on the first season of MTV's dating show "Are You the One." There was an instant connection between the two and ultimately the "Truth Booth" revealed that they were a perfect match.

During the reunion special Ethan dropped to one knee and proposed to the Texas gal and shortly afterwards the two announced their surprise pregnancy. Ethan and Amber made things official and got married in October.

On Saturday, Amber told her Twitter followers that she was finally in labor (baby Diamond was due on Dec. 17).

"Been in labor all day- counting down the hours to meet our beautiful daughter. It's been the most painful yet magical day of my life!" she wrote.

"Amber is such a trooper, couldn't be more in love and more proud of my wife and soon to be mother of our first born. #thediamonds," Ethan added on his own Twitter account.

Early Sunday evening, Ethan made the announcement that their baby girl had arrived.

"Proud father of our new 7 pound 8 ounce baby girl," he tweeted.

The couple hasn't released a name yet but earlier this month they told fans in a YouNow video that they had a few names in mind

"We're not 100 percent sure until we hold her in our arms," Amber said.  

Update: Amber announced on Twitter the baby's name is Scarlett Avery Diamond.
