The pair dated on and off for years, but solidifying the relationship was a step for Phelps as he tries to move forward from last year’s alcohol-related driving arrest. Phelps, 30, told Sports Illustrated for a story published last week that the arrest left him “not wanting to be alive anymore.” But he rededicated himself to his training and is focused on adding to his haul of 22 Olympic medals next summer in Brazil. Having an infant on hand in the months leading up to the Games might prove to be a distraction for Phelps, but certainly a welcome one." target="_blank">Phelps’ fast butterfly | Sobriety pledge | Michael Phelps-Ryan Lochte rivalry
