It looks like Mel Gibson’s ex-wife, Robyn Moore Gibson, might get dragged into the ongoing legal battle between Mel and ex-girlfriend Oksana Grigorieva. The Russian singer’s lawyers are looking to subpoena Robyn over her sworn statement that Mel was never abusive to her during their 28-year marriage, according to Radar Online. “Mel never engaged in any physical abuse of any kind toward me before, during, or after our marriage,” Robyn reportedly said. Grigorieva’s lawyers want to question her motivation for defending Mel.
