Amy Winehouse is a completely different person from who she was this time last year, her father says. The singer, 26, is doing well both inside and out – and that includes her recent breast enhancement.

On Wednesday, Mitch Winehouse told British TV show This Morning that his daughter is, "Fantastic, fantastic. Her boobs are great as well." He then smiled and said, "I shouldn't have said that should I? She looks absolutely fantastic."

Asked if the operation really cost $56,000 per reports, he shrugged, "I don't know. I didn't have to pay for it – that's all I know. Whenever I see her, she says, 'Dad can you give me a couple of hundred.' [But] I didn't have to pay for the boobs. I don't know."

It has been a turbulent year for the singer, who is now working on her third album. She has been through a divorce, cleared of assault charges and spent many months in St Lucia as she sought to get healthy. Her taxi-driver father said that she is faring well and "has not been sick now for a year."

But the battle is ongoing. "There is no total recovery. It's a recovery. It's a slow, gradual recovery," he said. "If you look back to where we were a year ago, you know we are in a different planet. We are in a different space and a different time and a different person. We all are. We're all recovering."

The singer's father spoke on TV a day after he addressed Members of Parliament, telling them that his family had been fortunate to afford the best clinics and doctors when seeking treatment for Amy. The special committee met because he is making a documentary about families coping with drug problems, and he was imparting some of his experiences and anecdotes culled during his research.

His advice for families coping with addicts? "The best thing we can do for our loved ones who are addicted is to maintain that normal family atmosphere. Why should they feel guilty? When the person has recovered and wants to reenter the family they don't want to see a family that's destroyed, and that can happen."
