Prince Andrew now has to deliver the cash after settling the civil sex abuse case with accuser Virginia Giuffre - and Prince Charles is said to be helping him with the millions he now owes.
He is letting his brother borrow £7 million as the Queen also helps out privately according to The Sun.
An insider told the paper the family plan to "take a little from here and a little from there" while Prince Andrew plans to reimburse his mum and brother in two months when he sells his ski chalet in Verbier, Switzerland.
