Example would not work with Cheryl Cole because she's not "cool".
The 28-year-old rapper is not "big" on duets and does not think he would be able to work with the British singer because she makes "cheesy" records, which he does not want to be involved with.
He said: "I'm not really big on duets. I work with cool people. Cheryl Cole, well, there are certain people who . I make cool dance music. I don't make cheesy pop stuff. There are some people who I wouldn't work with, not because I've got anything against them but because they're not right."
Instead, the 'Kickstarts' hitmaker prefers Nicole Scherzinger - who sensationally replaced Cheryl on the judging panel of the US version of 'X Factor' - because he believes she looks better than the 27-year-old Girls Aloud star.
He told BANG showbiz: "Nicole Scherzinger or Cheryl? Scherzinger. Why? Because she's got a bit more meat on her."
