BEIJING, August 1 (Xinhuanet) -- Former California governor Arnold Schwarzenegger reportedly has reunited with his estranged wife Maria Shriver for his birthday by having a lunch with her and their two sons. The ex-actor turned 64 on Saturday, July 30, and was snapped riding in the same car with his estranged wife. Words are that the couple went for some retail therapy at Barney's in Beverly Hills together.

Before they went shopping together, Arnold and Maria had lunch at his favorite restaurant, Cafe Roma, with their two sons, Patrick and Christopher. The birthday guy was seen "smiled a lot" during the Saturday outing.

California Governor Arnold Schwarzenegger and his wife Maria Shriver (R) attend funeral services for Italian film producer Dino De Laurentiis in Los Angeles November 15, 2010.

Arnold and Maria are in the middle of divorcing. Maria filed for divorce in early July after Arnold admitted to fathering a love child.

On July 25, the "Terminator" star himself submitted revised divorce documents that remove his original request to terminate the court's jurisdiction to award his estranged wife financial support.
