She also writes an advice column in the popular rock magazine Revolver, alongside musician Vinnie Paul. Scabbia is featured in a Megadeth song, "À Tout le Monde (Set Me Free)". She also featured on "The Theory of Everything", an album from Arjen Anthony Lucassen's Ayreon project, with which she is cast as the Mother. She is also the featured artist in the Apocalyptica song "S.O.S. (Anything But Love)" and another version of the Alter Bridge song "Watch Over You". Scabbia has said that the biggest compliment that a fan could pay her would be to remark on her vocal abilities. Her highest note ever hit is claimed to be an A7. Scabbia performed a duet with the Italian ex-singer of Linea 77 Emiliano Audisio on the track "Beautiful Lie" to be part of the soundtrack for the 2013 Italian film Passione sinistra.
