"Our message is simple. Don't buy her stuff until she's better," E!Online quoted one of them, as saying.

"We've all hung out with Britney a lot. We've seen her at her best and at her worst. And we aren't doing this to be mean.

"We're doing this out of concern, for herself and for her boys. They need a mother figure and right now, they don't have that."

The group also accuses Britney's record label Jive of turning a blind eye to her erratic behavior because she continues to make them money.

"They can see she's in pain, and they don't care," says the source.
