The 71-year-old's calendar sees the star in a number of poses, including some topless, and it's proving so popular it's outselling a number of A-List celebrities.
As well as heartthrob Justin Bieber, Take That, Cheryl Cole, Kylie Minogue and Michael Bublé are also trailing in Sir Cliff’s wake.
His is the third best-selling celebrity calendar this year, according to Amazon, only beaten by One Direction and JLS who are first and second respectively.
