‘Survivor’ Stars Rob
and Amber Mariano
Welcome Their Fourth
Daughter, Adelina Rose

Who needs to vote people off the island—when you can bring people on your island?!

Survivor alum Rob Mariano (A.K.A. “Boston Rob”) and his wife and former cast mate, Amber, welcomed their fourth child, a girl named Adelina Rose on Friday, June 20.

Four must be Rob’s lucky number—not only does he have four daughters now, but he also won Survivor on his fourth appearance on the reality show!

He announced Adelina’s arrival on Twitter, writing, “We are thrilled to announce Adelina Rose Mariano 12:51 am June 20, 2014 Mom and baby are doing great! #4for4”

Rob also shared the heartwarming moment Adelina met her big sisters, Lucia, 4, Carina, 3, and Isabetta, 2.

“Lucia Rose, Carina Rose, and Isabetta Rose are beyond excited to welcome their new sister Adelina Rose!” he wrote.

Amber and Rob aren’t the first stars to debut their kids on social media—and we doubt they’ll be the last! Check out eight other babies who made their debut online!
