Amy Winehouse makes prison suicide pact with husband Blake

Troubled British singer Amy Winehouse has made a prison suicide pact with her husband Blake Fielder-Civil, it has been revealed.

24-year-old Amy, who is due to be quizzed by cops over Blake's charges of assault and allegedly perverting the course of justice, could face prison if she is linked to the conspiracy to clear Blake.

Amy has reportedly vowed to kill herself if she is parted from her husband by a lengthy jail sentence.

A source is quoted as saying: "Amy has had her problems but she is really teetering on the brink. She has hatched a suicide pact with Blake. If they are both handed lengthy jail sentences she is determined they will end it together rather than face five years apart.

"She can't live without Blake and her family are worried sick. This could finish her off. She isn't strong enough for prison life."

The singer, who famously sang the lyrics "They tried to make me go to rehab - I said no, no, no," must present herself for questioning this week. She will be finger-printed and asked to give DNA samples, as police believe she may be linked to crucial documents seized after Blake was arrested.

A police source said: "This is a very significant development in the investigation."

Barman James King was allegedly offered a £200,000 ($400,000) bribe to change his story, after Blake and his friend Michael Brown were charged with GBH following a brawl which severely injured King.

Blake Fielder-Civil is currently locked up in London's Pentonville prison. He will face trial early next year.
