J.R. Martinez, 29, has already had quite a life. The U.S. Army vet was burned on more than 40 percent of his body when his Humvee hit a roadside bomb while serving in Iraq. But Martinez didn't let the incident stop him. He now works as a motivational speaker, appeared on the soap "All My Children," and competed on — and won! — "Dancing With the Stars" in 2011. Still, the hero has recently taken on a new challenge: fatherhood. His girlfriend Diana Gonzalez-Jones gave birth to daughter Lauryn Annabelle, nicknamed Belle, on May 2. "The minute she was born I was like, 'This is where I'm meant to be.' I felt excitement and love and it was all about her," he told People.
