While Amy Winehouse and her fans will be celebrating her winning streak at the Grammys, one star remains not so impressed.

Fellow jazz singer Natalie Cole, daughter of legendary crooner Nat King Cole, has said she is "disappointed" the troubled star was honoured with five gongs at the prestigious music awards.

She said: "I don't think bad behaviour should be rewarded, so I was disappointed." And when asked if she thought the Back To Black star should have won any Grammys, she replied: "No, I don't think she should have."

Winehouse won record and song of the year for her autobiographical hit Rehab and picked up best new artist, best pop vocal album for Back To Black and best female pop vocal.

The 24-year-old is as famous for her turbulent lifestyle as her talent and is currently getting help for her drug addiction at the Capio Nightingale rehab centre in London.

But 58-year-old Cole believes she is speaking from experience, after battling her own demons with substance abuse in the 80s, temporarily putting her career on hold.

She said: "I know because I was in that situation. I lost five years of my life and my career because of drugs. So you don't play like that."
