The 30-year-old rapper hasn't dropped any music for the last 18 months, but she admits she's beginning to plan her third LP and is expecting it to be ready by the end of 2014.

Speaking to MTV, she said: "I'm definitely working. I'm very excited at what I've been coming up with. I already started, I didn't tell anybody because I didn't want to jinx it and stuff but I already started and I'm going home tomorrow to really start."

The 'Super Bass' hitmaker is remaining tight-lipped about who she is working with, but she's confident the people she has selected for her new studio album will put a different spin on her music.

She explained: "I'm really excited and the people that have been working with me now, have been people that I haven't worked with before so it's like they're bringing a new sound to the album that I've never experimented with and plus, I got so much to talk about."

Nicki insists she'll be?content to work with when it comes to penning her lyrics because she's been through so much since she last released any music.

She said: "I've experienced so much in the last year and a half that there is so much for me to talk about and I know my fans are going to be excited about it."
