Rob And Amber Mariano Fourth Child: 'Survivor' Couple Welcomes Baby Girl Adeline Rose

Rob and Amber Mariano have welcomed their fourth child.

According to reports, the former reality stars welcomed a fourth daughter, Adeline Rose, on Friday, June 20. In the days that followed, Rob (also known as “Boston Rob") shared a couple of photos of the baby on his Twitter account.

“We are thrilled to announce Adelina Rose Mariano 12:51 am June 20, 2014,” Ron wrote with the first photo of himself, Amber and the baby, according to a June 24 report by In Touch Weekly. "Mom and baby are doing great! #4for4.”

Rob and his wife Amber began dating in 2003, during their time on Suvivor: All-Stars. On May 9, 2004, during the show’s live finale, they became engaged. One year later, Rob and Amber were featured in a two-hour wedding special, which aired on CBS on May 24, 2005. The special was titled, Rob and Amber Get Married.

Following their nuptials, Rob and Amber moved to Pensacola, Fla. and started a family. Their first child, daughter Lucia Rose, was born in July 2009. In Dec. 2010, daughter Carina Rose arrived, followed by Isabetta Rose in May 2012.

In Rob’s second photo, his three oldest daughters were seen gazing down at their new baby sister. In the caption, Rob told fans, “Lucia Rose, Carina Rose, and Isabetta Rose are beyond excited to welcome their new sister Adelina Rose!”

Four is a lucky number for Rob. Not only does he have four daughters, he also won Survivor during his fourth appearance on the long-running reality show.
