London, Nov 1 Paris Hilton's glamorous Halloween party ended in a fiasco after her security guards refused to let in hundreds of her VIP guests.

The 28-year-old socialite, dressed as Dorothy from the Wizard of Oz, was spotted screaming at the security men standing at the entrance to her fashionably gated estate.

"These are important people, just let them in for f***'s sake. You're ruining my f***ing party," the Mirror quoted an angry Hilton, as shouting.

However, tight security checks saw more than 60 luxury sedans stuck in a traffic jam for hours around Mulholland Drive in LA. (ANI)
