Reality TV show stars Rob and Amber Mariano just welcomed a baby girl last Saturday, May 5.

“Isabetta Rose was born on Cinco de Mayo,” Amber tells People magazine.

“Isabetta was born with a full head of brown hair and blue eyes,” the proud mom adds. “She still has all of her hair almost six weeks later, and her eyes are still as blue as can be. Her sisters can’t get enough of her. They always want to hold her and I’m not sure who gives her more kisses — her big sisters or her parents!”

So why the interesting name? “We never name our babies until we actually meet them. When we saw her for the first time that afternoon, we knew it was the perfect name for her.” She also adds, “Rob really liked the idea of all of our girls sharing the same middle name. Many cousins on his side also share Rose as their middle name.”

This is the third baby and girl for the couple. Baby Isabetta joins older sis, Lucia Rose, 2½, and Carina Rose, 18 months.
