Media mogul Simon Fuller– who also manages David Beckham – has become a father for the first time.

The British businessman – and former Spice Girls manager – is one of the most powerful men in broadcasting and is estimated to be worth £350 million.

His wife, Natalie, gave birth to a girl weighing 8lb 6oz in Los Angeles.

Mr Fuller, who established shows such as American Idol, which will soon begin its 10th series, set up a new company, XIX Management, last year.

He made his fortune with his former firm 19 Entertainment. This year’s Sunday Times Rich List has said he is reckoned to be the sixth richest music millionaire in Britain.

A statement from his firm said the couple – who married in 2008 – were “delighted” and added: “Both mother and baby are in good health.”
