Washington, April 1 : Britney Spear's alleged voicemail message for her lawyers, depicting her frustration at her father''s conservatorship order, has been leaked online.

Her father Jamie was granted control over the pop princess' legal, financial and personal matters last year following her public breakdown that sent her packing to a rehabilitation centre.

The leaked clip was said to have been left by the singer in January, in which she appears to inform her attorneys about her father's threat to distance her from her sons, reports Contactmusic.

A transcript of the tape allegedly said: "Hi, my name's Britney Spears. I called you earlier. I'm calling again because I just wanted to make sure (it is known) that during the process of eliminating the conservatorship that my father has threatened me several times, you know, he''ll take my children away.

"I just want to be guaranteed that everything will be fine with the process of you guys taking care of everything - that things will stay the same as far as my custodial time. That''s it, bye." (ANI)
