Music mogul Simon Cowell's house, worth 35 million pounds, was burgled in the presence of his family.

The thieves stole cash and jewellery from Cowell's home in Holland Park, West London, with his girlfriend Lauren Silverman and son Eric inside on Friday, reports mirror.co.uk.

According to a source: `It was clearly a very traumatic incident. Simon is just relieved that his family was safe and all right. Their safety is his number one priority.`

Police rushed to the luxury house, but the burglars had fled.

`The X Factor` judge's home was targeted before as well in March 2012. His stalker Leanne Zaloumis had wielded a brick and hid on a shelf inside his wardrobe.
