The troubled beauty fears the sex tape of her one-night stand, filmed without her knowledge will end any hopes of ever getting her little boys back.

“This is bad, bad news for Britney. They say it takes three bad blows to send you over the edge. Britney’s had about half-a-dozen in two years.�?

“She lost her kids and now a sex tape is up for grabs. This the kind of thing can drive a person to suicide,�? a Brit pal says.

The mystery man says Britney “doesn’t hold back�? in the video because she did not realize she was being filmed.

One adult film industry boss says:

“I’ve been told it’s dynamite stuff…..We’ve had Britney without her knickers and topless with another girl, but from what I’ve heard we haven’t seen anything yet.�?

“It’s Britney exposed like we’ve never seen her before.�?

“The film is worth millions but Britney has the kind of money it will take to stop it being shown.�?
