"No U Hang Up" is a song written by Arnthor Birgisson, Rami Yacoub and Savan Kotecha and performed by The X Factor winner, Shayne Ward. The song was released as a double A-side single along with "If That's OK with You".

Although the single was released as double A-side, the official Irish chart company, IRMA, did not combine the two singles when they charted, due to two different digital singles being available separately. "If That's OK with You" charted at number one, while "No U Hang Up" entered at number fourteen, later climbing to number eleven. In the UK, the single entered the chart at number two, being beaten to the top by the Sugababes song, "About You Now".
