Thieves broke into a property in north-west London owned by the singer and stole cash, jewellery and electronics while a relative slept upstairs.
The burglary took place six days before an alleged thief crept into Simon’s £35 million home in Holland Park, west London, around three miles from Rita’s house in Brent.
Rita Ora (Ian West/PA)Police are investigating the break-in at Rita’s home but no arrests have yet been made.
The 25-year-old musician reportedly divides her time between the £1.3 million semi-detached property and a town house in west London, although her whereabouts at the time of the burglary are unknown.
A Metropolitan Police spokesman said: “Police in Brent were called to an address in NW10 at 5.54am on Saturday November 28 following reports of a burglary.
“An investigation is under way. No arrests have been made.”
Simon and partner Lauren (Ian West/PA) Officers were called to Simon’s home in the early hours of December 4 to reports of a robbery while he slept upstairs with partner Lauren Silverman, 38, and their 21-month-old son Eric.
A 37-year-old man was arrested later that day and questioned. He was released on bail until a date in early January pending further inquiries, police said.
Simon and Rita will appear on The X Factor’s live final on Saturday and Sunday nights at 8.00pm on ITV.
