Amy Winehouse Final Hours: Determined to have a big one on Friday night

Details are emerging regarding British singer Amy Winehouse's final hours, who was discovered dead Saturday.

The 27-year-old who sings Rehab had fought a long battle with alcohol and drug addition.

The exact cause of death is not known and an autopsy has yet to be carried out.

Reports are claiming that the soul singer was buying drugs including cocaine, ecstasy and ketamine in Camden late at night, just hours before her death.

The People reports that a source said Amy seemed determined to have a big one on Friday night. She was out in Camden on Friday evening, but seemed determined to carry on the party back at her flat.

Sunday Mirrow reported that Winehouse's friends believe she died from an ecstasy overdose mixed with alcohol. She could do cocaine till until the cows come home. But this was obviously a dodgy pill.
