Nigella Lawson has upped the stakes in her split with Charles Saatchi — by consulting the top divorce lawyer who acted for Paul McCartney.
The TV chef has reached out to Fiona Shackleton — who was famously soaked by Heather Mills when she lost her case for a huge payout from her Beatle ex.
Shackleton — who is Nigella’s cousin — is known as the “doyenne of divorce” and represented Prince Charles in his split from Diana as well as Madonna when she broke up with director Guy Ritchie.
Mom-of-two Nigella, 53, began speaking to her shortly after learning art tycoon Saatchi, 70, had announced their divorce in a Sunday newspaper, according to pals.
