Friends of troubled singer Amy Winehouse have intervened, setting up camp at her home to make sure the "Rehab" hitmaker doesn't do anything to wreck her own mental health.

According to U.K. tabloid The Sun, the 22-year-old singer's friends have canceled commitments and camped at her home in Camden to stay with her round the clock.

A source says, "No one wants to leave Amy on her own - she's in a very fragile state at the moment."

"Her most loyal friends are terrified she is going to do something which she can't overcome."

"She's been to hell and back already but some fear she's going to get worse before she gets better."

Meanwhile, her outspoken dad Mitch has made his stage debut on Saturday. He performed Frank Sinatra classics in front of 300 listeners in Chiswick, singing the classic hits for almost an hour.
