Country star Reba McEntire's husband and son have gone into business together as talent managers. The singer's husband, NARVEL BLACKSTOCK, was forced to close the management division of his Starstruck Entertainment eight years ago (98) to concentrate on masterminding his wife's career. But now he's back in business with his son BRANDON, who has been working as country trio Rascal Flatts' tour manager for the past four years. The Blackstock's first signing to their revived management company is country singer Blake Shelton.
