Lady Gaga's new album will be "insane."

The "Marry the Night" hitmaker is already working on the follow-up to Born This Way - which was released in May 2011 - and her co-manager, Vincent Herbert, thinks it will defy all expectations.

"There's a lot of work to come, [I'm] very excited about it. [It's] just an insane, great record. She's on tour right now, but it's just going to be a great record. Look out for the unexpected when it comes to her. We're doing it on the road right now, so it's a little hard, but it's going to be great," Vincent said, speaking to website That Grape Juice.

Gaga is currently undertaking a two-year Born This Way Ball world tour but won't let that get in the way of her plans to make a new album, as parts of Born This Way were also recorded on the road. Her single "Marry The Night" took shape with producer Fernando Garibay whilst on her previous tour in 2009.

"I just kind of got on the American leg of the tour ... and she goes, 'I want to write another song that can define where I'm at with this album and my life. I go back to the studio bus; I'm just working on parts ... and then, two hours later, she comes offstage and she goes, 'Do you have something to play me?' And I go, 'I do, actually.' So I played her the instrumental for 'Marry the Night,' and she goes, 'Open up a mic,' Garibay said. "She starts laying down the whole song, like, off the cuff ... right off the stage, using the energy of that crowd and going into the studio, it was amazing. I can't compare it to anything."
