TMZ reports Bruce Jenner is dating one of Kris Jenner ‘s best friends … Our Jenner sources tell TMZ … Bruce has hooked up with Ronda Kamihira … a 51-year-old mother of 2. We’re told Kris is “extremely upset” that Bruce is dating Ronda, and — as one source puts it — “It really stings because Ronda never told Kris she started seeing Bruce.” A Jenner source tells us the talk in family was that Ronda was weirdly becoming “Kris’ single white female.”
