AMY Winehouse's persistent drug use has left the troubled star's nose so "weak" she is concerned that it's about to fall off, according to a new report.

"Amy knows that her nose is next to fall apart — she admitted to me that it feels weak at the bone," a source tells Fox News columnist Neil Sean.

Amy herself has addressed the nose issue. "Yeah, it's a problem, but it's my problem so leave it," Sean quotes her as saying.

Meanwhile, Amy's friends are said to be so worried about the Grammy Award winner they are keeping watch over her 24/7.

According to a report from earlier in the week, the Rehab hitmaker's pals have been forced to give up their prior commitments and stay with Amy at her Camden, North London home to ensure she doesn't do anything she might regret.

A source told The Sun, "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."

The singer, 25, is also facing arrest after allegedly punching dancer Sherene Flash last week.
