Miley Cyrus fears her home could have been burgled again.

The 'Wrecking Ball' hitmaker, who had $100,000 worth of purses and jewellery stolen from her mansion in Studio City, Los Angeles, last year, is working with police after her assistant found personal items had been moved at the property over the weekend.

According to TMZ.com, police were alerted around midnight on Saturday (31.05.14) after the assistant came home and noticed some of the star's belongings weren't in the same place.

A source said there was once again no sign of forced entry to the property and officers are looking through the 21-year-old singer's CCTV footage to try and find out if anyone has taken anything from her home.

A fingerprint unit is also set to visit the star's property to look for clues and Miley was not at home when it is thought to have happened.

Miley was clearly upset today (01.06.14) as she took to Twitter to post: ''ya know when you just cry in the shower for no reason (sic),'' although she didn't say whether or not her mood was related to the possible break-in.

The pop star's home was targeted in November 2013 on the weekend of her 21st birthday and thieves stole her vintage Chanel purse, which featured in photographs when Miley was seen smoking a suspicious-looking roll-up cigarette at the European Music Awards last year.

Sources said at the time she was ''really shaken up'' and ''extremely upset'' after the personal items were taken in broad daylight and she also avoided running into an armed intruder in 2012 when a man forced his way into her home carrying a pair of scissors.

Luckily, the singer wasn't in at the time and her employees were able to call the police quickly and have the man arrested.
