David Guetta was so desperate to work with Nicki Minaj he pursued her for a year.

The French DJ and producer - who is behind some of biggest hits of recent years, including Flo Rida's 'Club Can't Handle Me', Akon's 'Sexy Chick' and Black Eyed Peas 'I Gotta Feeling - is inundated with calls from artists begging him to collaborate, but is such a huge fan of Nicki he found himself begging her to record 'Where Them Girls At'.

He told MTV news: "I'm a really huge fan. To be honest, it's very rare that I call artists - most of the time they call me. I've been chasing her for a year because I really wanted to work with her.

"The first time you're in the studio with someone, it's sometimes difficult. She was being a little shy or reserved, you know. And then I played that record and she started to jump from her chair and scream. And she was like, 'Wow, I love this!'"

While the song - which also features rapper Flo Rida - is currently shaping up to be a hit around the world, David is upset he has had to rush release it after hackers stole the vocals to the track.

He said: "I was not supposed to release the record so soon. Hackers stole the a capella and someone produced some music around it and put my name on it and put it on the Net. So it was horrible, I really didn't like the music, and people thought it was me.

"I had to React to this by releasing the record without any promotion. Without a video, without anything. And what is really incredible and crazy is that the record is number one on iTunes in every country in the world. It's absolutely unbelievable."
