Former X-Factor winner Leona Lewis has praised Amy Winehouse, calling the singer “an amazing artist”.

In an interview with Parade, Lewis, who won the 2007 edition of X-Factor, praised Winehouse’s talent but said she was worried about her public image.

“A performer’s privacy is taken away. The media are always there. You can’t make your mistakes in private,” Lewis said.

“I have the advantage of a great support structure. I get honest opinions from my family and friends.

“They aren’t always telling me what I want to hear, but the truth helps keep my head straight.”

Lewis will perform at the same event as Winehouse for the first time later this month.

Both singer’s are billed to appear at Nelson Mandela’s 90th birthday celebrations in Hyde Park on June 27th.

Razorlight, Queen and Annie Lennox are also scheduled to appear at the event, which will raise money and awareness for the 46664 aids campaign.
