Lady Gaga's 2009 hit Bad Romance has become the second million-selling single of her career.
The track, from her debut album The Fame Monster, is about love gone awry and features a catchy chorus.
It went straight to the top of the charts on its release before being knocked off after a week by Rage Against the Machine's Killing in the Name.
But after selling more than one million copies, the song is on course to becoming one of the UK's biggest selling singles of all time.
According to The Official Charts Company, the New York-born star is only the 16th artist ever to achieve more than one million selling single in the UK.
Bad Romance now joins I Feel Love by Donna Summer, Bohemian Rhaosody by Queen and Anything is Possible by Will Young.
Blurred Lines by Robin Thicke and Daft Punk's Get Lucky crossed the one million mark in July.
Mummy Monster previously reached the million milestone with her debut single Poker Face.
Lady Gaga is battling Ellie Goulding to get to No 1 in this week's charts with her new single Applause, the first track to be taken from her third album Artpop.
