Drug-n-drunkie Amy Winehouse had a pretty bi-polar reaction to the news that her former hubby, fellow addict Blake Civil-Fielder, has knocked someone up. Wino is back to terrorizing the peaceful island of St. Lucia, where she first assumed Blake’s underage girlfriend, Francesca Morralee, was the mom-to-be. While downing champagne at a resort bar, she started off happily blabbering: “I knew he’d got her pregnant. I had this feeling Blake was having a kid.”

Wrong! Seems that heroin addict Blaaaake has impregnated a fellow junkie! Amy wasn’t thrilled to hear that Blake’s child was conceived IN REHAB with heroin addict Gilleen Morris, 31, not Francesca.

Amy proceeded to lose her tenuous grip. “That better be a mistake or I’ll beat his head in. Oh great, he’s had it with some … I don’t wanna know – don’t tell me any more.”

Then the real show started: Amy began pounding her chest, convulsing and grabbing her stomach in pain. After she downed some Xanax calmed down, she expressed some addled happiness for Blake.

“All I wanna know and all I need to know is that my baby is having a baby. I never talk to him, I’m never going to see him again but we’re like best friends. I have to cut him out of my life because he has to cut me out… so me and Blake can’t be friends but you know what? He’s having a kid and that is amazing.”

Not to be outdone, Amy then declared that she TOO wanted to have a baby. Actually, she wants to have twins. Fortunately, Amy’s years of chemical craziness probably sent her eggs packing long ago. We can only hope.
