A few days ago, it was revealed that singer Bobby Brown had filed for guardianship over his daughter Bobbi Kristina‘s estate (click HERE if you missed that).

While reports vary about her condition, Bobbi Kristina remains hospitalized after being found unresponsive in her bathtub over 11 weeks ago.

As Bobby Brown seeks to control his daughter’s fortune, he certainly won’t get it without a fight from Whitney Houston‘s family.

Cissy Houston, Bobbi Kristina’s maternal grandmother, is reportedly planning to battle her former son in-law ‘to the grave’ over her daughter’s fortune.

“Cissy Houston will fight this to the grave.”

The source also stated that they knew all along that Bobby Brown was after his daughters dough:

Since day one, all of the Houstons have been waiting for Bobby to try and get Bobbi Kristina’s money and they knew it was just a matter of time.

No one is surprised that he is making a grab for her money.

Wow… this family feud won’t end well.
