Actor Orlando Bloom lost jewellery worth an estimated $500,000 (£333,330) when burglars broke into his Hollywood Hills mansion on Wednesday night (15Jul09).
The Pirates of the Caribbean star was in New York when the heist took place.
According to TMZ.com, two pricey watches are among the items stolen by thieves, who reportedly gained access to the Los Angeles property through a window.
Police sources tell the website the break-in did not appear to be "a typical burglary"; no arrests have yet to be made.
