Lady Gaga still has "a lot of work left" to do on her ARTPOP album.

The "Judas" singer is preparing to release her third full length album - rumored to be a double - after her Born This Way Ball world tour wraps up in March. Producer and collaborator Zedd, who has been working on tracks with Gaga, told MTV news, "We've been working on it for over a year now. There's still a lot of work left, so we're definitely gonna work on this project for the next month. I did about 10 ideas, and they were all between almost finished songs up to the piano. And then when we were on tour together in Asia for almost two months, we had a lot of time to go back and forth and pick the ones we really like and work on them. But they're still all really rough - it could be five, it could be 10."

The US leg of the Born This Way Ball kicked off earlier this month and came to the Staples Center in Los Angeles on Sunday, where Gaga delivered a typically flamboyant show, with some 12 costume changes and elaborate stage sets including a meat grinder, her castle and the singer emerging by birthing herself from a inflatable belly flanked by fishnet-clad legs. She also talked about her past as a go-go dancer and how her friends used to strip in order to pay their college fees. "I'm really just one of the highest paid strippers in the world, naturally," she told the crowd.
