Dolly Parton's sister Freida Parton is sharing an update after she asked fans to pray for her sister's recovery a week after the singer postponed her upcoming Las Vegas residency due to health issues. "I want to clear something up," Freida, 68, wrote in a Facebook post. "I didn't mean to scare anyone or make it sound so serious when asking for prayers for Dolly."Freida said that Parton, 79, has "been a little under the weather, and I simply asked for prayers because I believe so strongly in the power of prayer.""It was nothing more than a little sister asking for prayers for her big sister.
