LOS ANGELES: Forget the octagon, Ronda Rousey is buzzing about a ring after announcing her engagement to fellow MMA fighter Travis Browne. Rousey flashed the diamond and made the announcement in a paparazzi video shared by TMZ Sports . Browne says in the video that he popped the question under a waterfall in New Zealand last week. The 30-year-old Rousey says they plan to get married 'soon,' but that they're just in the beginning stages of planning a wedding. Rousey also doesn't have a date for her next fight. She suffered a humiliating defeat to Amanda Nunes in December in a comeback bid after losing her UFC title to Holly Holm in 2015.
