Lindsay Lohan’s days of designing heart-shaped pasties and sequined leggings could be numbered, fashion insiders tell The NY Post’s PageSix Column.

The former A-list actress is in danger of losing her gig as a celebrity advisor with French fashion house Emmanuel Ungaro after her Spring/Summer 2010 collection was ripped with scathing reviews during its debut at Paris Fashion Week last month.

Earlier this month, Ungaro himself, who hasn’t had any contact with the house that bears his name since leaving in 2005, panned Lohan’s work for the brand an “embarassment.” Apparently, he isn’t alone. Ungaro’s chairman, Asim Abdullah, reportedly wants Lohan gone and is trapped in a bitter battle with CEO Mounir Moufarrige, who hired the former box office “Mean Girl.”

“Asim wants her out now,” a fashion insider who has seen e-mails between the two executives tells Page Six. “Department stores in the States have already told him they won’t be picking up the line if Lohan remains a collaborator, so it’s a serious issue.”
