Britney Spears is working on ''fun, cheeky, sexy'' music.

The 33-year-old singer is busy in the studio working on the follow-up to 2013's 'Britney Jean' and has teased fans will see her fun side on the collection, hinting she has also been collaborating with other female stars.

She said: ''We're having fun right now. I'm working with some women who are amazing writers. I have ballads and, of course, dance music--fun cheeky sexy stuff.''

Meanwhile, the 'Toxic' hitmaker - who released her first single from the album, 'Pretty Girls', earlier this year - has also had her hands full with her Las Vegas 'Piece of Me' show at The Axis in Planet Hollywood, and having recently celebrated 100 shows at the venue, is unsure whether to continue performing there beyond 2015.

Questioned on whether she will extend the residency, she admitted to E! News: ''I'm not really sure. I haven't made up my mind. I really love doing the show. It's a lot, a lot of fun but I'm kind of torn right now. I don't really know what I want to do.''

Britney was speaking at the Teen Choice Awards at Los Angeles' Galen Theater, where she urged young people to be ''fearless'' with their fashion after picking up the Candie's Choice Style Icon award.

She said: ''Fashion has always been something I love to experiment with.

''It gives us all a chance to express ourselves and our own personalities and to shine in our own way. To all the teens out there watching, be fearless in your choices and don't be afraid to be yourself.''
