Reality TV star Heidi Montag has dismissed reports suggesting she has joined the cast of addiction counselor Dr. Drew Pinsky's show "Celebrity Rehab."
 
Online gossip linked "The Hills" star to the new season of the show, which features celebrities attempting to deal with all manner of addictions.
 
One report suggested the blonde had already checked in to Dr. Drew's rehab house in Pasadena, California, earlier this week after struggling with a pill-popping problem.
 
A source tells X17online.com, "Heidi was dropped off at the house two days ago by a friend. She is going to be on season five with the rest of the cast."
 
But Montag tells People.com the story is not true: "No, I'm not joining the cast."
 
But she will be watching as Lindsay Lohan's father Michael and actors Bai Ling and Jeremy Jackson face their demons on the show: "It sounds like a great cast and I can't wait to watch this season!"
