India, June 10 -- Actor Angelina Jolie and ex-husband, actor Brad Pitt's son Knox Jolie-Pitt graduated from high school on June 5, but this happy moment turned into an internet spectacle due to his graduation speech. In the videos that surfaced online, the 17-year-old is seen dressed in his graduation cap, robe and several floral leis, as he stepped up to the podium and let the crowd know where he was headed after the ceremony. "Tonight, I'm gonna be fighting at Total Sonic Knockout 5 at 12:45 am, so catch me. I'm gonna knock 'em the f*** out. Let's go!," he announced. The proud mother Angelina was seated in the audience along with her other kids - Knox's twin sister, Vivienne, brothers Maddox, 24, and Pax, 22, and sister Zahara, 21, who just graduated from Atlanta's Spelman College in May. While Angelina was seen filming her son on her phone as he took the stage, Brad was again missing as he was at Zahara's graduation. Living up to his promise though, Knox took to the ring at a Downtown Los Angeles club and a video obtained by TMZ showed him exchanging kicks and punches before winning the IKF Point Muay Thai Technical event. Angelina stayed on for the fight too, watching from the crowd alongside Knox's twin sister Vivienne as he took the win. Knox and Vivienne, the youngest of Jolie and Pitt's six children, will turn 18 on July 12. HTC...
