Reba McEntire and Brandon Blackstock's dad, Narvel Blackstock, split a decade ago, but the country superstar was still there for the family in the months leading up to Brandon's death. "Reba has spent more time with the Blackstock crew in the past year than in years prior," an insider exclusively tells Us Weekly, adding that past years were "contentious." "They really came together," continues the insider. Earlier this year, McEntire, 70, spent time with the Blackstocks at the Houston Livestock Show and Rodeo, where the Grammy winner was one of three headliners.
