Lady Gaga and Justin Bieber are now unlikely rivals: the two are soaring towards one billion views on YouTube, and whoever gets there will be the first star to hit the mark in the website's history.

Lady Gaga averages 2.5 million views a day on the site, whereas Bieber averages 4 million. In comparison, Kanye West gets 200,000 hits a day, and Michael Jackson nets 600,000 hits a day.

At this rate, Lady Gaga appears to have Justin beat thanks to her head start, and will surpass the billion hits mark around October 20. Justin could match the mark sometime in November. Of course, now that attention has been brought to the "race," fans of both artists will no doubt be vying to bring their chosen artist to the top first.
