Music cred: They don't call her the Queen of Latin Pop for nothing. Gloria Estefan has sold over 100 million albums worldwide and won seven Grammys. That's easy credibility.
Why he/she would be good: Estefan has appeared as an "American Idol" mentor and worked well with the kids. She also appeared in the movie "Music of the Heart," which was all about mentoring. Add in the different audience she'd bring to "X Factor" and she'd be a fine choice.
Why he/she could suck: Estefan may not provide the currency that Simon is looking for as "X Factor" attempts to compete with "The Voice."
Chances: With more substance than Nicole and less crazy than Paula, Estefan could be an interesting pick, but only if there's a "hotter" and "younger" name for FOX to trumpet as well. 20 percent?
