Amy Winehouse’s alleged lover Alex Haines has been fired after he was allegedly caught on camera taking drugs.

The temperamental singer had been accused of cheating on her incarcerated husband Blake Fielder-Civil with Haines, and subsequently severed ties with the assistant of her manager.

Haines has since allegedly been caught on camera smoking drugs, according to the Daily Mirror, and Winehouse's management firm Metropolis has confirmed he is no longer an employee.

A source reveals: "Alex was asked to resign. The last thing Amy needs hanging around her are more (drug) users. Alex was supposed to help her and he crossed the line.

“Alex was a good friend to Amy but he caused massive rows for her with Blake. He couldn't stand hearing they were sleeping together."

A spokesman for Winehouse says: "We can confirm that Alex is no longer working for Metropolis or for Amy Winehouse."
