Lohan, 23, is to appear on Thursday night's edition of "The Insider."
The New York Daily News said a commercial for the episode implies the "Freaky Friday" and "The Parent Trap" star is overwhelmed by the shoes and clothes in her home, possibly because of a troubled relationship with her estranged father, Michael.
"Is Lindsay Lohan a secret celebrity hoarder?" Nash is seen asking in the advertisement.
"I just need to get rid of... stuff," Lohan said in the clip. "That's personal stuff that I have to work on."
