Lady Gaga’s First Number 1
Exactly 5 years ago, Lady Gaga hit number 1 on Billboard‘s Hot 100 chart with her debut single, “Just Dance,” which also featured Colby O’Donis. The song would spend three weeks at the top of the chart.
In the half-decade since, Lady Gaga has hit number one twice more, with “Poker Face” and “Born This Way.”
