One month ago, Ted Williams was a homeless man with a "golden voice" living on the streets of Columbus, Ohio. But one chance encounter and a Youtube video gone viral launched Williams into overnight superstardom. He had an emotional reunion with his mother and even found work doing a voice-over gig for a Kraft commercial.

But going from homeless to Hollywood is no easy transition. After a fiery altercation with his daughter, Williams was convinced by Dr. Phil to check into rehab after only one week of fame.

Now, less than two weeks after beginning treatment for drug and alcohol dependency at a center in Texas, Williams has left rehab against medical advice, TMZ reports.
