Katy Perry just crashed the ultimate boys club. After hanging around in the mid 900 millions for a while, KP's "Dark Horse" video crossed a major milestone on Tuesday morning (June 9), when it became just the third video ever -- and first by a female artist -- to notch more than one billion views.

Katy was pretty psyched, writing, "Guys. Wut. Dark Horse has reached 1 BILLION views?! I seriously ❤️ ur balls & ur fingers for dem clicks."

Though the official view count on YouTube was still stuck at 985,302,706 at press time (and a bit closer at 998,787,700 on Vevo -- the counter read is sometimes a bit behind the actual totals), Perry slipped into third place on the all-time list behind Psy's "Gangnam Style" (an untouchable 2.3 billion) and his label mate Justin Bieber's 2010 smash "Baby" with nearly 1.2 billion clicks.

Even as she smashes the glass ceiling, Katy's knocking on the door again with the #4 all-time video, "Roar," which had more than 954 million views at press time. But she might have some competition soon from sometime rival Taylor Swift, whose "Blank Space" is currently at #5 with more than 923 million.

Two other women could be gunning for the billion benchmark soon, with Shakira's 2010 FIFA Wold Cup song "Waka Waka (This Time For Africa)" at #9 (867 million) and Meghan Trainor's "All About That Bass" rounding out the top 10 (866 million).
