Ben Goldsmith accuses Rothschild wife of caring more about PR than 'devastated children' But their eight-year marriage ran into difficulties earlier this year, amid claims that Mrs Goldsmith was leading an "increasingly nocturnal" lifestyle since she went into the music industry with a company called Roundtable Records. She had a brief fling with a New Orleans rapper called Jay Electronica during a trial separation from her husband, and although they were briefly reconciled the marriage ended dramatically last week. Mr Goldsmith claimed to have discovered incriminating messages on his wife's phone and during a showdown early last Wednesday at their home, he was arrested and admitted slapping his wife and injuring her leg with a child's toy. Details of their split first appeared in the Sunday newspapers, while Mr Goldsmith was on holiday in Italy with his children and his mother, Lady Annabel, prompting his estranged wife to issue a strongly worded statement in response. In it, she claimed that "false and inaccurate" information had been give to the media "in a deliberate attempt to damage Kate and her businesses." She said she was "devastated" and that "her main concern now is for her children." On Monday afternoon, Mr Goldsmith used his Twitter account to hit back. In a message to his 6,000 followers on the social networking service, he wrote: "@kateroundtable has hired Project Associates Ltd to fix her reputation (bit late surely?). How about focusing on her devastated children? He added "Ps, in case you missed it" and posted a link to the original story about the affair. Mrs Goldsmith's spokesman declined to comment on the claims. Earlier in the day, Jay Electronica had posted his first messages on Twitter since the scandal broke. In a tweet sent from a computer in "Westminster, London," he wrote "Lightnin done struck the s---house and the whole town is stinkin," a quotation he attributed to his grandmother, whose funeral he had been attending in Los Angeles. Shortly afterwards, the rapper posted the message "#LoveIsOnTheWay." It also emerged that the Goldsmiths" marital home in Kensington went on sale last month for £20m. Described as a "unique" villa, it has more than 5,600 sq ft of living space spread across four floors as well as a summer house in the exceptionally long rear garden. Built in 1860, it retains some original features as well as solid oak flooring and a vast open space on the lower ground floor containing a kitchen, dining room and living room that looks onto the lawn. Earlier in the year it had been claimed that the couple were hoping to make a private sale and move somewhere smaller nearby in order to reduce their mortgage payments. But now the house is being advertised by two different estate agents. Mr Goldsmith has moved out but as the falling-out with his wife turns ever more bitter, the home or the proceeds of its sale are likely to be fought over in the divorce courts.
