She left the Radiators and was replaced in February 2006 by Jesse Booth, and went on to form a band of divorcées named PreNup with Hothouse Flowers guitarist Fiachna Ó Braonáin. In 2012, O'Riordan completed a BA in Psychology, followed by an MPsychSc 2013 in UCD. She is currently completing a PhD in Psychology in UCD.

In February and March 2020 Poguetry played an eight date tour of the US. Since 2020 O'Riordan has hosted a weekly radio show, "The Rocky O'Riordan Show" on U2-X Radio, an artist-branded channel which is part of SiriusXM.
