When Pitbull visited Lopez to promote his latest album Planet Pit, we finally got to the bottom of how the hip hop star really got his name. "Pitbulls are outlawed in Dade county," he dished to Lopez, "So I'm the only Pitbull with papers!" Sure, it was funny, but it's also true! In the uncomonly candid interview, we also learned about Pit's relationship with his father and how they got so close right before Armando Sr. passed away. It was a touching tribute from the rapper and gave us an authentic glimpse into how he became the man he is today: Mr. Worldwide!
