AMY WINEHOUSE dating ALEX HAYNES?

Amy, who today been cautioned for common assault, now plans to divorce BLAKE FIELDER-CIVIL.

Her friends and management are said to be “over the moon” that she has fallen for 24-year-old Alex, who is her manager’s assistant and is described as a “clean-cut mummy’s boy” from Gloucestershire.

A source said: “It is a relief that it’s finally out and they have everyone’s 100 per cent backing. Alex is a good boy. He doesn’t smoke or take drugs. He isn’t a big drinker. Amy has really fallen for him.”

The Rehab singer had tried to keep the couple’s month-long romance under wraps for fear of how Blake, 25, would take the news in London’s Pentonville prison, where he is remand on trial-fixing charges.

A pal of the star said: “Amy doesn’t want the truth coming out because she doesn’t want him reading things that will upset him in case he tries to do anything silly in jail.

“She does care about him still and has been trying to be seen to support him through his jail ordeal — but she just doesn’t want to be with him any more.”
