Dolly Parton has turned down the chance to become a Tv talent show star several times - because she doesn't have what it takes to judge others.

The country queen reveals she has been at the top of producers' wish lists for American Idol and The X Factor, but so far there hasn't been a deal she has even considered.

She tells In Touch magazine, "I've been asked to do American Idol and The X Factor almost every time there's a new season, but I'm very sensitive."

There is, however, one U.S. singing show she'd at least think about - The Voice.

She explains, "You don't have to judge that much - and I hesitate to judge people."
