Lady Gaga's monster hit Poker Face has officially reached one billion YouTube views.
The 2008 single is the third Gaga song to join the billion club, following Bad Romance and Shallow.
Poker Face is one of her most successful releases to date, topping the Billboard Hot 100 in April 2009.
It remained on the chart for 40 weeks and is still one of the best-selling singles of all time.
The track brought Gaga her first Grammy for best dance recording and was also nominated for record and song of the year.
