Katy Perry just smooched her way to No. 1, and into the history books.
Her single "I Kissed a Girl" leapfrogged over Coldplay to top Billboard's Hot 100 singles chart, becoming the 1,000th No. 1 hit of the rock era.
Perry landed the millennial No. 1 by selling 235,000 digital copies and surging seven spots to No. 12 on the Hot 100 Airplay chart. Though her music leans pop, the racy singer is racking up spins at several alt-rock stations as well, and she's a fixture on this year's Vans Warped Tour.
