Maria Shriver and ex-husband Arnold Schwarzenegger let bygones be bygones and came together to celebrate their son Patrick Schwarzenegger's college graduation.

The estranged couple reunited for the commencement ceremony at USC and posed for a picture of the three of them together.

"Wouldn't be anywhere without these two," the 22-year-old grad captioned the Instagram snap. "Thank you for everything and love yah [sic] both."

His sister Katherine, 26, shared the same photo and wrote, "Proud parents. SO MUCH LOVE."

Arnold and Maria both took to their own Instagram accounts to praise their son for his achievements. "Patrick, I'm so proud of you," wrote his dad. "You have grown into a great man – physically and mentally – and I can't wait to see what you do next. Congratulations. I love you."

Maria and Arnold, who also have another son Christopher, 18, and a second daughter Christina, 24, ended their 25-year marriage in 2011 after news surfaced that Arnold had a child with their longtime housekeeper.

Nice to see them getting along for the sake of their children!
