This happy news comes just weeks after Phelps admitted to Sports Illustrated that he was in a "dark place" following his second driving under the influence arrest in Sept. 2014. The dad-to-be's first DUI arrest was back in Nov. 2004, when he was 19 years old.
"I was in a really dark place ...not wanting to be alive anymore," he recalled. "I look back now ...I lived in a bubble for a long time."
"It's probably the most afraid I've ever felt in my life," he said of checking into a rehab facility center.
