The legendary singer was approached to join both shows as a judge over the years but admitted the only TV talent search she would ever consider appearing on is `The Voice` because it is more nurturing to its contestants. Dolly told In Touch magazine: "I`ve been asked to do `American Idol` and `The X Factor` almost every time there`s a new season. "[On `The Voice`] you don`t have to judge that much and I hesitate to judge people." Dolly previously revealed she will always be grateful to Whitney Houston for making her song `I Will Always Love You` famous and credits her friends and God with preventing her from going down the same road as the tragic singer, who drowned following an accidental overdose in a hotel bathtub in February. She said: "I thank God every day for that song - and Whitney made it popular worldwide. It`s a very simple song, really, as simple as anything I`ve ever written. "I`ve always had good and close friends, and a spiritual faith. God will take the wrong people and things out, and teach me to have the right people and the right things. "Some people don`t have that, and that`s where it can go wrong."
