Nicole Scherzinger Makes First Appearance Since Replacing Cheryl Cole on 'X-Factor' (PHOTOS)
Although there is no official confirmation as to why Cole left the show, sources told The Hollywood Reporter that Cole didn't mesh with the other judges.
The source said:
"There was no spark. It was nobody's fault. It just didn't work."There's no word on if Cole will be used at all for the U.S. edition of X-Factor, which premieres in September.
Meanwhile, Paula and Simon have apparently reignited their spark. The former American Idol judges were spotted last month gearing up for the first round of X-Factor auditions -- hugging and kissing as they reunited. We can't wait to see what these two have in store.
