Heidi Montag start to ‘Celebrity Rehab’: Heidi Montag, who first gained recognition when she starred on the MTV reality series "The Hills", is reportedly a new addition to the cast of season 5 of "Celebrity Rehab". It has been reported that former reality star Heidi Montag had been dropped last week and the filming had begun without her. Along with Heidi Montag, the other new member to join the sober house is Sean Young.

The season 5 of "Celebrity Rehab" includes New York Mets pitching great Dwight "Doc" Gooden, "Real Housewives of D.C." housewife Michaele Salahi, actress Bai Ling, Michael Lohan and "Baywatch" star Jeremy Jackson in the cast. As Heidi Montag has never been in news for any drinking or drug addictions, it can be assumed that the new bird in the VH1 show is checking in possibly to deal with her addiction of pain killers due to multiple painful plastic surgeries.

According to sources, Heidi Montag is already causing drama in the house. The plastic surgery girl has only been there for a week and she has already had one mental breakdown drama in the house.

As sources have reported, Heidi Montag was dropped at the "Celebrity Rehab" house by a friend (not Spencer Pratt) two days ago. As a part of the season 5 cast, Heidi Montag joined the house and was listed to share room with Michaele Salahi, about which she threw a fit. Heidi Montag showed up an absolute meltdown and was taken out of the room she was to share with Salahi. The major drama of Heidi Montag forced the show producers to change the room accommodation just to lodge her in the house.

With a rollercoaster ride in personal life, especially her relationship with Spencer Pratt and her numerous plastic surgeries and their after-effects, Heidi Montag knows well how to stay in headlines and surely her new stint with Dr. Drew would put up a lot of drama.
