Former A Shot at Love star Tila Tequila had committed to be a Celebrity Rehab cast member early last week, while Shauna Sand -- the ex-wife of reality retred Lorenzo Lamas -- also recently signed on to participate.
Former Laguna Beach star Jason Wahler was reportedly "very close" to an agreement to appear on the series, and Bone Thugs-N-Harmony rapper Bizzy Bone -- whose real name is Byron McCane -- also expressed interest in participating to receive treatment for marijuana and alcohol addiction.
While the VH1 reality series was also reportedly interested in casting actress/singer Liza Minnelli and Dutchess of York Sarah Ferguson, both have denied any involvement in the show.
