Britney Spears' ex-husband Kevin Federline has shelved his plans to become a reality TV star out of respect for the troubled pop star and her family. The rapper/dancer is developing a project all about his life as a single dad of the two young sons he had with Spears during their brief marriage. But sensitivities have prompted him to rethink the series after the Toxic singer was committed to a Los Angeles hospital for psychiatric tests last week (31Jan08). A source says, "Everything is on hold."
