Kelly Clarkson is not quite done breaking away from ex Brandon Blackstock.

Amid a more than three-year legal battle, the talk show host has filed a countersuit against her former husband and his father Narvel Blackstock's management firm months after they appealed a decision by a California agency that ordered the group to repay the "Heartbeat" singer $2.6 million that they had received in commissions when Brandon worked as her manager.
