Paris parties in see-through nightie at the Playboy Mansion!

London, Aug 13 : American socialite Paris Hilton was spotted being her social self at the recent Midsummer Night's Dream party held at the Playboy Mansion.

Hilton was photographed looking stunning, as she partied in a see-through nightie and knickers combo, and with her hair extensions down she looked like a life-size Barbie at the bash in California, the Sun reported.

The heiress, whose boyfriend Benji Madden was nowhere around, slipped into the skimpy outfit and danced around to her heart's content.

The party, held by Hugh Hefner, is an annual event, and a summer highlight for Californian celebrities.

Meanwhile, Hilton was in the spotlight recently for her fluctuating chest size.

A fact, which has caused many to be perplexed, as she seems to have a fuller bust at one time and at another a flat one.
