Lady GaGa is stunned by the success of her chart-topping debut 'Just Dance' - because it took her just 10 minutes to write the track.
The song reached number one in six countries, including the Ireland, and even earned the singer a Grammy nomination.
Gaga told Britain's Heat magazine: "It's been unbelievable the way the song has crossed over into the mainstream. It took 10 minutes to write!
"I think it's because it's a happy record. Maybe the record will be appreciated more now there are lots of people who are going through rough times, losing jobs and homes."
