Pete Doherty

When Doherty's son Astile with fellow musician Lisa Moorish was born in 2003, Pete was forbidden from seeing his baby on account of his heroin habit at the time. This father didn't begin to see his child until 2008, after he had reportedly overcome his drug use and was rumored to be entirely clean. I do hope Pete has managed to remain sober and in contact with his son in the mean time.
