The 'Russian Roulette' singer insists the LP - the follow-up to 2007's 'Good Girl Gone Bad' - is edgier and is more personal than her other releases.

She said: 'We made a great album, which was my intention in the first place. That makes this a classic album for me.

'It's very edgy. 'Good Girl Gone Bad' was all about me at that point of my life. It had attitude and an edge and this next album takes it up a notch.

'I want to evolve and keep changing and I want my music to reflect that.'

With her new musical direction the 21-year-old star has evolved her style, although Rihanna is adamant it was not a conscious decision to make herself sexier.

The pop beauty – who has previously admitted many of the things on the album were inspired by her ex-boyfriend Chris Brown - said: 'A lot of people say to me, 'You got sexier. Your image has changed.' But that really isn't it. I'm just dressing how I feel. I'm more comfortable in my skin. I basically dress to my mood.

'There are times when I like to dress up and be very sexy and feminine and then other times I'm like a tomboy because I just want to wear something comfortable.'
