Lindsay Lohan allegedly threw a tantrum when she was asked to promote rival Paris Hilton’s fashion line.

Lohan agreed to appear at an event to push the Scandinavian Style Mansion in Los Angeles, according to U.S reports.

But when she arrived at the glitzy event she discovered she would actually be helping promote Hilton’s own accessories line.

An unimpressed Lohan then ordered her flacks to have all of the adverts with Hilton’s name on them removed, it was claimed.

“Why would Lindsay ever walk down a carpet of another celebrity’s fashion line when she was never told before the event?” a pal told Life & Style magazine.

Lohan’s representatives say that the star has since received an apology from event organizers.

But Claus Hjelmbak, owner of the Scandinavian Style Mansion, was less than impressed. “The drama was unnecessary,” he told Life & style.
