London, July 28 : Amy Winehouse's father Mitch insists all is fine with the troubled singer after she punched a wall and burst out crying.
The 24-year-old's fist was bleeding and one of her nails ripped off in the act.
She also lashed out at her own security guards.
After the incident, she went out partying with 'Celebrity Big Brother' contestant Aisleyne Horgan-Wallace.
Winehouse is reportedly suffering from lung disease Emphysema and her face is also showing marks of a skin disease called impetigo.
"With her pale face and smeared make-up, she looked like something out of Michael Jackson's 'Thriller' video. It was really sad to see," The Sun quoted an onlooker, as saying.
However, Mitch said: "Amy is doing fine."
