Fed up with hubby Blake Fielder Civil publicly humiliating her, singer Amy Winehouse has reportedly contacted her lawyers, telling them that she doesn't owe him anything.
Apparently, the 'Back to Black' hitmaker is determined that Blake won't see a penny of her estimated 10-million pound fortune and is building up a cast-iron case to prove her point, reports the Mirror.
A source revealed: "What with the moral grounds for complaint - his public bad-mouthing of her - Amy decided to reduce her initial offer of '100,000 pounds take-it-or-leave-it', to zero.
"She's adamant he's been living off her coat-tails for too long and does not deserve a penny more."
The insider added: "This is set to become the most acrimonious celebrity split of 2009. The knives are out.
"Blake has been bad-mouthing her and Amy feels totally betrayed. She supported him the entire time he was banged up first time around, and this is the thanks she gets.
"When he was released from jail and packed off to rehab, he didn't even inform her. The first she heard of it was when the clinic invoiced her for 36,000pounds - she still has the fax to prove it.
"On top of this, Amy spent in excess of half a million pounds on Blake's legal team in the past year, as well as on presents and surprises for him."
The couple's imminent divorce comes just 18 months after their fun wedding in Miami.
