"I think understanding the music video process is really important for all of us as artists," she says. "It's our one and only chance to really, really connect with the fans on screen and for them to see us with our work and putting a picture and a song a face."

So it's very fitting that Britney has become the latest artist to have VEVO Certify her music videos for Til The World Ends and I Wanna Go now that they've delivered over 100 million views across VEVO's platforms.
