“Although this is not what we ever imagined, we will always have four incredible reasons to celebrate our years together: our sons,” says Cora. “We are forever parents to our boys and are jointly committed to raising them in a peaceful, nurturing and healthy environment.”

But despite this statement, TMZ reports that there could be a custody battle brewing.

According to the gossip site, Jennifer has filed for full physical custody of their four children – all boys. Cat Cora has reportedly requested joint custody.
