Patrick Schwarzenegger found a way to reunite his mom and dad for the evening!

Arnold and Maria's son, who arrived in his bright orange hot rod, invited his soon-to-be-divorcing parents to a graduation get-together party at Toscana in Brentwood to celebrate his buddy going away to college.

X17online was the first to bring you the news of the estranged couple reuniting. An X17 photographer who witnessed Maria and Arnold inside the restaurant tells us:

    "They kept their distance. It wasn't like Arnold and Maria were making googly eyes at each other or anything. They were there for the benefit of their son but there was no reconciliation going on. They exchanged a few words cordially though."

Despite partying together in Brentwood, Maria is rapidly moving forward with her divorce from the former California governor. This encounter at Toscana is the first time the two have seen each other since Arnold's love child scandal broke in May.
