Maria Shriver and her estranged cheating husband, Arnold Schwarzenegger, had an awkward run-in at the Diane von Furstenberg store in LA when both showed up to support their daughter Katherine. She hosted an event at the Melrose Avenue store for her charity, Best Buddies International, on Thursday night. It was carefully choreographed, but the exes still ended up bumping into each other. Maria arrived before Arnold, flanked by two female friends. She bought a few items and snapped photos with Katherine before leaving the store and waiting for her car. Our spy said, “Arnold showed up with two male friends while she was waiting for her car to pull up from the valet. They made eye contact as he got out of the car. It was awkward. Arnold approached Maria to say hello as her car pulled up. They talked for almost a minute.” Maria drove away as Arnold headed into the store, where he had a stiff Svedka cocktail. We’re told that once inside, Arnold was in great spirits. “He was smiling and mingling with guests,” a spy said.
