Robbie Williams with Pet Shop Boys are a collaborative effort between Robbie and Neil Tennant/Chris Lowe of the Pet Shop Boys. Together they recorded two tracks for Robbie's Rudebox (2006) album, "She's Madonna" and "We're The Pet Shop Boys", the former released as an international single. In 1998, Robbie previously recorded a cover of the former Pet Shop Boys single "I Wouldn't Normally Do This Kind Of Thing" as a B-side for "Let Me Entertain You". Later the same year, Neil Tennant (along with Neil Hannon of The Divine Comedy) provided backing vocals for the Robbie single "No Regrets".
