Burglars targeted X Factor judge Rita Ora less than a week before Simon Cowell's mansion was raided, it has been reported.
Thieves broke into the singer's north-west London home and stole cash, jewellery and electronics while a relative slept upstairs, according to The Sun.
The burglary took place six days before an alleged thief crept into X Factor boss Cowell's £35 million home in Holland Park, west London, around three miles from Ora's home in Brent.
Police are investigating the break-in at Ora's home but no arrests have been made.
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."
The 25-year-old musician's whereabouts at the time of the burglary are unknown.
Officers were called to Cowell'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.
