Arnold Schwarzenegger turned 73 years old surrounded by his children — and ex-wife Maria Shriver!

Arnold celebrated his 73rd birthday on Friday, July 30. Sometime over the birthday weekend, he gathered with Maria and their four kids for cake and family time. Eldest son Patrick shared a lovely photo of the reunion on Monday.

Arnold Schwarzenegger's marriage to Maria Shriver ended in divorce

Schwarzenegger and Shriver were married for 25 years when they separated in 2011. Shortly after news of the separation, it was revealed that Schwarzenegger had fathered a child, Joseph Baena, in an affair with a former employee.

The divorce was finalized in 2017, but it appears as though the Schwarzenegger-Shriver family of six can still gather on amicable terms for special occasions. What's more, Arnold and Maria will for the first time become grandparents when daughter Katherine, who's pregnant, gives birth to her first child with Chris Pratt.
