Madonna's manager Guy Oseary was on the receiving end of a slice of cake as Madonna's team celebrated her album 'MDNA' hitting No.1.

Her new album topped the charts in a host of countries around the world, including in the US and the the UK.

A video has been posted of Madonna being treated to a surprise party to toast the album's success.

She is seen sheepishly entering a room before an assembled crowd greets her with adulation.

The Queen of Pop is then seen cutting a piece of celebratory cake before planting it straight onto the face of her manager, Guy Oseary.

She appears to then say: "That's for making me work so hard, motherf**ker."
