The 32-year-old star was targeted by a group of girls, who tried to steal from her collection of purses at her home in Malibu, California, last weekend, when she was throwing a goodbye bash before heading to Ibiza.
She tweeted: "I have bad luck when it comes to thieves... They tried to steal my new collection of @PHpurses from my Malibu house."
According to TMZ.com the perpetrators tried to make a quick dash after grabbing purses, bikinis and framed pictures but were scared and dropped the items on their way out.
While it is not known whether the thieves were apprehended, the items were recovered as a valet attendant spotted the discarded possessions down the road from the house and turned them in to the police.
This isn't the first time the heir to the Hilton Hotel chain has been targeted. Sofia Coppola's new movie 'Bling Ring', which stars Emma Watson, is based on the terrifying theft of £1.2 million worth of jewellery and other valuables from Paris' home five years ago.
