Lady Gaga's "Born This Way" has become the fastest-selling single ever on iTunes.
Apple says the song's racked up more than a million downloads in five days.
The dance track has hit Number One on iTunes in 23 countries.
It's the title track of a new album to be released in May.
However, Lady Gaga may not be not be No 1 in Sunday's Big Top 40 chart - Adele is currently No 1 after her stunning BRITs performance.
