Popstar Lady Gaga has become the first artiste to score a billion views on YouTube, beating off hot competition from teen idol Justin Beiber. The "Poker Face" singer faced serious competition from Bieber in the last few months as the pair battled to land the coveted title, but won the race this weekend. For a brief moment, though, it looked as if Beiber might win: indeed, in the past three months, he averaged 3.98 million views per day to Gaga's 2.04 million. "We reached 1 billion views on YouTube little monsters! If we stick together we can do anything. I dub u kings and queens of YouTube! Unite," Gaga wrote on her Twitter web page. But don't count the rather annoying Bieber out just yet: his "Baby", a duet with Ludacris, is the most-viewed video on YouTube with over 366 million visits. He is behind with 962 million views in total. But by November 1, he should also reach the billion mark, reported Contactmusic. The third place is occupied by 'King of Pop' Michael Jackson.
