Just Dance by Lady GaGa has remained at the top of the UK singles charts for a third week.
The New York star's single held off the challenge of rapper Kid Cudi - who remained at number two with Day 'N' Nite - to retain the number one spot.
The 20-year-old, real name Joanne Stefani Germanotta, was nominated for a Grammy for Just Dance, and also finished sixth in the BBC's Sound of 2009 list.
Grime star Tinchy Stryder debuted at number three with Take Me Back while girlband the Saturdays remained in the top five with their third single Issues.
