Both Clarkson and McEntire are reportedly missing tapings of The Voice after Blackstock’s August 7 death from melanoma (a form of skin cancer). Seasons 28 and 29 of the show are filming pre-taped episodes this summer, but McEntire and Clarkson are going to have to sit a few out, according to The U.S. Sun.

The singer was scheduled to appear at Miranda Lambert and Parker McCollum's Band Together Texas event taking place on Sunday to support those affected by the floods in July.
