In 2010, Adler collaborated with his former Guns N' Roses bandmate Slash on the latter's self-titled debut solo album, which was released in April. He appeared on the track "Baby Can't Drive", along with Red Hot Chili Peppers bassist Flea, Alice Cooper, and Nicole Scherzinger. The song was featured on an expanded edition of the album released by "Classic Rock". The following July, Adler's Appetite—consisting of Adler, singer Rick Stitch, guitarists Michael Thomas and Alex Grossi, and bassist Chip Z'nuff—released the single "Alive", in conjunction with the release of Adler's autobiography "My Appetite for Destruction: Sex, and Drugs, and Guns N' Roses". In December, the band released two more singles, entitled "Stardog" and "Fading". In 2011, following another relapse, Adler participated in the fifth season of "Celebrity Rehab with Dr. Drew".
