The British chef's fall out with his wife's father Chris Hutcheson hit the headlines in October (10) when the businessman left his post as CEO of Gordon Ramsay Holdings (GRH).
Hutcheson is suing his son-in-law for $3 million (£2 million), while Ramsay went on the attack by speaking publicly about the family feud, insisting he feels "betrayed" and "let down" by his in-laws.
Ramsay has now further cut ties by buying Hutcheson's shares in their Petrus eaterie, which they opened together in 1999.
A rep for Ramsay says, "Petrus is now owned by the GRH group, a commercial settlement on this issue having been reached with Chris Hutcheson. Gordon Ramsay is extremely committed to and proud of the restaurant."
