Britney Spears has revealed her next record will be her "most personal" album yet.
The pop star is returning to music with her eighth album, which she admitted will be a revealing one.
"Really excited 2 give u a taste of my new album... can't wait 2 share what I've been working on. Going to be my most personal album ever :)," she tweeted.
The 31-year-old singer recently released her latest single, Ooh La La, an upbeat track featured in the upcoming animated Smurfs sequel, The Smurfs 2. Will.i.am is an executive producer on the album, which is expected to be released later this year.
Britney previously admitted that she felt under pressure to come up with a successful follow-up to 2011's Femme Fatale, tweeting: "Thank you SOO much for voting my new music as the Most Anticipated Event of 2013 on @Billboard! Lot of pressure ;)."
The singer has been getting ready for her new Las Vegas show, which is set to open in the autumn.
"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, Tony Martinez," she told Shape magazine.
"The performances 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."
