David Guetta is working on some "top secret" songs with Kelly Rowland.

The 'When Love Takes Over' DJ - who recorded the hit record with the former Destiny's Child singer - has revealed he has joined forces with the "amazing" songstress once again for her upcoming album.

He revealed to Digital Spy: "I'm actually already working with her on her next album. We've just done a few songs at the moment and it's all fairly top secret. We've become really close friends over time. I think she's an amazing singer - one of the best in the industry - and a great person too."

The French star - who has also collaborated with Black Eyed Peas, Estelle and Akon - is also keen to work with 'Poker Face' hitmaker Lady Gaga and pop sensation Madonna.

He said: "Lady Gaga's amazing. I met her last month and she's like a crazy genius! She's a great writer, producer and can play so many instruments. It's incredible how successful she's been in such a short amount of time. I met with one of her producers, RedOne, and we're going to try and work together. If we could sort it out, we could come up with something crazy!

"I would love to work with Madonna. It will probably happen very soon actually. It's all in the early stages and I'm not allowed to speak about it yet!"
