Ben Goldsmith, the multi-millionaire son of the late financier Jimmy Goldsmith, has separated from his wife Kate, the heiress of the Rothschild banking dynasty.
Thirty-one-year-old Ben confirmed the split to The Daily Mail, saying: "I'm pretty shell-shocked by everything. All I am thinking about now is my children."
The couple have a daughter, eight-year-old Iris Annabel, and two sons, seven-year-old Frank James Amschel and four-year-old Isaac Benjamin Victor.
News of the split came after Ben was taken away from the couple's Notting Hill home by police following an argument over his 29-year-old wife's supposedly deepening friendship with an American rapper.
The financier was released after being given a caution.
Rap artist Jay Electronica, who now lives in London, is one of music producer Kate's clients.
