Clarkson has kept a low public profile since Blackstock's death on Aug. 7 at age 48 from cancer. Following Blackstock's passing, Clarkson postponed her Studio Sessions residency at the Colosseum at Caesars Palace in Las Vegas and pulled out of her planned appearance at Miranda Lambert and Parker McCollum's Band Together Texas flood relief benefit.

In addition to starting production on the new season of the Emmy-winning Kelly Clarkson Show, the singer also returned to The Voice after missing some episodes in the days that followed her ex-husband’s passing. Carson Daly opened up about supporting her and Reba McEntire — who was Brandon Blackson’s stepmother — during this difficult time.

The first-ever "American Idol" winner Kelly Clarkson broke her silence on social media after the death of her ex-husband Brandon Blackstock.
