The exes of the Kardashian-Jenner family were all in one place on Wednesday night. Rob Kardashian's ex-fiancee, Blac Chyna, attended the iGO.live launch event at the Beverly Wilshire Hotel, and in a bizarre turn of events, hung out and posed for photos with Khloe Kardashian's ex-husband, Lamar Odom. This comes just weeks after Odom told ET that he's praying for Rob, and hoping that the 30-year-old reality star will "live and learn through" his recent relationship drama.
