Bobby Brown and Whitney Houston may want to consider another sit-down with Diane Sawyer. Police — responding to a domestic abuse call Sunday night at the couple's Atlanta home — found Houston with a cut upper lip and a bruised cheek. She told officers that her hubby hit her during an argument, and then hopped on a plane to California. Formal charges have not yet been filed. In the meantime, Houston is considering putting Kevin Costner back on her payroll.
