Lindsay Lohan has opened up about her new obsession - she`s a secret celebrity hoarder. The troubled actress agreed to let TV cameras into her Hollywood home to show off the extent of her latest problems - the place is strewn with boxes of unopened shoes and freebies. The "Mean Girls" star, who has fought a string of personal battles in recent years, tells TV news show The Insider she knows she has to do something about her hoarding - because it`s beginning to take over her life. She says, "I just need to get rid of stuff... It`s personal stuff that I have to work on." The TV special will air on Thursday.
