62 of 261: Rob Mariano, aka Boston Rob, and wife and fellow 'Survivor' alum Amber, welcomed their third daughter, Isabetta Rose, on May 5, 2012 in Pensacola, Florida, where they live.

The two are also parents to Lucia Rose, 2, and Carina Rose, who is 18 months old.

Mariano began his reality television career as the scheming bad boy on the fourth season of Survivor in 2002. Sparks flew when he met season 2 contestant Amber Brkich on the reality show's first 'All-Stars' season in 2004.

Their collaborative efforts on the show to outwit, outlast and outplay the rest of the players led Amber to win the game - and Rob to propose on the finale. They married in 2005 and their wedding was made into a TV special. The couple went on to star together on several more reality shows, including two seasons of 'The Amazing Race' and the short-lived series 'Rob and Amber: Against the Odds'.

Mariano competed on 'Survivor' two more times and in 2011, began co-hosting the History channel travel series 'Around the World in 80 Ways' with monster truck driver Dennis Anderson.
