Blake Fielder-Civil is planning to leave Amy Winehouse for his mistress, reports.

Blake — who is currently in London’s Pentonville Prison awaiting trial for grievous bodily harm and perverting the course of justice — has reportedly proposed to his mystery new girlfriend and has told friends he wants a massive divorce settlement.

The 25-year-old has enjoyed a string of secret visits from the mystery blond, who is friends with Amy, and on occasion has passed messages between the estranged pair. According to Britain’s The Sun newspaper, Blake reportedly told his mistress: “Just say the word and I’ll dump Amy.”

He is set to ask for a divorce settlement of at least £3 million — demanding £250,000 for each month of his year-long marriage — despite being jailed for almost half of it.
