The VH1 reality series is attempting to land Sarah Ferguson for its upcoming fourth season in an effort to add some star power to the show's cast, RadarOnline reported Tuesday.
Ferguson is currently at the center of an international scandal after she was recently caught on camera trying to sell access to ex-husband Prince Andrew for $734,000. She subsequently stated on The Oprah Winfrey Show that she had "been drinking" when she made the offer.
Former A Shot at Love star Tila Tequila had committed to be a Celebrity Rehab cast member early last week, while former Laguna Beach star Jason Wahler was also reportedly "very close" to an agreement to appear on it.
In addition, Bone Thugs-N-Harmony rapper Bizzy Bone -- whose real name is Byron McCane -- expressed interest in participating in Celebrity Rehab to receive treatment for marijuana and alcohol addiction.
While RadarOnline reported attempts to cast Ferguson for the fourth season are in the "very early stages," VH1 executives feel she would help bolster Celebrity Rehab's lineup.
