Britney opened up to E! News’ Catt Sadler about her new single, album and Vegas.

“I just knew I liked it the first time I heard it,” Brit says of her new single “Work *****.”

But her album is not about being hot in a bikini or driving fast cars. Instead, Brit says it’s her most personal work yet because of her breakup from ex-fiance Jason Trawick.

“I had a lot to say… I just got with writers I was really comfortable with. You come from a cooler place when you actually have hardships.”
