Gary Oldman's son has defended him against allegations of domestic abuse from his ex-wife.<br /><br />The 'Darkest Hour' actor was recently slammed by Donya Fiorentino, who claimed their marriage was a "nightmare" and accused the British star of abusing her emotionally and physically, before using his power and fame to get custody of their children, Gulliver and Charlie.<br /><br />However, after the former model blasted Gary, Gulliver has penned an open letter to defend his dad and branded the claims against him "false".<br /><br />In her interview, Donya claimed the 59-year-old star had hit her with a telephone in front of their sons in 2001, but Gulliver insisted the alleged incident "didn't happen".<br /><br />Last September, Gary tied the knot with writer and art curator Gisele Schmidt.<br />
