Britney Spears is hard at work, and things are about to get personal.
"So excited 2 give u a taste of my new album... can't wait 2 share what I've been working on," she Tweeted. "Going to be my most personal album ever :)"
The 31-year-old recently released her latest single, "Ooh La La," an upbeat track featured in The Smurfs 2, and is getting in shape for her Vegas show.
"I'm doing 90 minutes of yoga twice a week in addition to a lot of cardio - hour-long sessions three times a week with my trainer," she revealed.
"[Vegas] won't be simple - they'll be a massive party from start to finish. And to pull this off, I have to be in top condition and running at full speed."
