Amy Winehouse's dad in fury over Blake Fielder-Civil

After a rumour that Amy Winehouse has hooked back up with her ex-husband of just weeks, Blake Fielder-Civil, her father is said to have discovered the pair together. Winehouse was said to have snuck Fielder-Civil into her home to avoid her security guard, who is under orders to bar him. But Mitch Winehouse went charging over to Amy's place after the guard alerted him to Fielder-Civil's arrival. Mitch then proceeded to eject the young man out of his daughter's home at Hadley Wood, North London, and allegedly threatened to "punch his lights out". A source said: "Mitch hates the fact he's reappeared – it's making him ill. It'll force him into an early grave. Blake begged Mitch not to hit him when he chucked him out. Mitch was absolutely furious, he still is. He can't believe Blake has wormed his way back into his daughter's life." Amy has been fraying at the seams since returning to the city life of London and legal actions. She divorced Fielder-Civil just last month. However, the singer was soon heard talking of Fielder-Civil as her man and her soulmate. Our source said: "He [Mitch] thinks it's the worst scenario for Amy. Just when she's starting to sort herself out, the man responsible for dragging her into the gutter is crawling back into her life. Mitch is praying history doesn't repeat itself. He is dreading the day he finds his daughter is back on hard drugs because of him. He's worried sick." Mitch in the Sky documentary Saving Amy said the pair "would kill each other if they got back together".
