Ego was the second single from the UK girl group The Saturdays second album, Wordshaker. It was subsequently also featured on the girls 3rd album/EP release Headlines. It was released on 3rd January 2010. The single peaked in the UK Singles chart at number 8. The song was accompanied by probably their biggest budget music video yet, as the girls played their alter-egos to bring down their nemesis. The song is a clear fan-favourite and is often performed at their own tours and summer festivals.
