Joan CollinsActress Joan Collins revealed that her very tight dress was the reason she had to be rushed to the hospital after she nearly passed out at an Oscar after-party.

The 77-year-old 'Dynasty' actress was reported to be wearing a purple figure-hugging dress by designer Georges Hobeika at the 2011 Oscars.

Page Six is revealing that Collins was at Graydon Carter's viewing party and dinner at the Sunset Tower Hotel when she started to feel faint.

Collins went and rested on a sofa at the hotel's bar, while her husband Percy Gibson, called for an ambulance. Collins was discreetly helped out of the back of the hotel.

She told the Daily Mail that the reason she could have fainted was possibly her very tight dress. "The truth was, I made the wrong decision to wear a very tight dress, and had something rather like a Victorian swoon."
