David Guetta enjoys bringing out Nicki Minaj's "full capacity as a singer."

The 'Sexy Chick' hitmaker has worked with the rapper on a number of tracks including 'Where Them Girls At' and 'Turn Me On,' and loves it when she sings as well as raps verses.

He told Vibe.com: "She's the no. 1 female rapper. But she can also sing, which adds something different. These are all the things that attracted me to her.

"I wanted to take her someone unexpected musically. I think the work we have done shows the full capacity of her as a singer. I'm in love with her voice! I'm looking forward to working with her more in the future."

David - who is behind some of the 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' - has previously told how he chased Nicki for months to get her to appear on 'Where Them Girls At.'

He said: "To be honest, it's very rare that I call artists - most of the time they call me. I chased 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!'"
