Lindsay LohanAfter kicking off about onions last week, Lindsay Lohan reportedly had a “hissy fit” at a party on Friday night because she didn’t know it was an event for Paris Hilton.

Lindsay is said to have hit the roof at the Scandinavia Style Mansion party in Beverly Hills on Friday after spotting an advertisement for Paris’ new range of handbags which was prominently displayed on the red carpet and finding out that the party was also to promote an alcoholic drink.

Lindsay’s spokesperson Leslie Sloane Zelnik yesterday explained the now sober Mean Girls star’s outrage occurred because she was ambushed when the facts came to light: “We were never told that Paris was part of the event. Nor did we know there was a liquor sponsor. She wouldn’t have participated.”

Zelnik added that Lindsay was also misled about the amount of photographers to be present at the party.
