Mitch Winehouse, Amy's father, believes that she died of after alcohol detox seizure.

Amy Winehouse's father Mitch is convinced he felt his tragic daughter's presence at her funeral after a black butterfly landed on pal Kelly Osbourne's shoulder during his emotional eulogy.

The Back To Black hitmaker was found dead in her London home on 23 July and she was laid to rest in a private service three days later.

Mitch Winehouse remembered the singer in a moving tribute, recalling a number of amusing stories from his daughter's childhood, as mourners such as Osbourne and producer Mark Ronson grieved.

But he's adamant Amy, who had been battling addictions to drink and drugs, had sent them a sign from above to show her loved ones she was now at peace.

In an interview with newsman Anderson Cooper, which aired on Monday, Mitch recalls, "When I did the eulogy at her funeral. As I got up to speak, a black butterfly came in… I had my head down 'cause I was reading, and I could hear people muttering and I thought the paparazzi had got in (sic).

"It (the butterfly) landed on Kelly Osbourne's shoulder, then flew around me… Have you ever heard anything like that in your life? It's incredible. Has anybody ever seen that?"

The singer was 27. A full inquest into the cause of her death is due to begin next month.
