Dina Lohan, mother of Lindsay, has come under fire for letting her youngest daughter Ali audition for a notorious porn film director.

Ali Lohan's audition for new movie Trolls was captured for reality TV show Living Lohan, but no one knew that Peter Davy, the man behind the film, was the director of X-rated movies like Voodoo Lust and Dreams in the Forbidden Zone.

Lohan's spokeswoman says: "Ali had no idea about Davy's past. If she did, she never would have auditioned for him."

Maybe Ali can star in a sequel of Lindsay’s film I Know Who Killed Me.
