May 1 (UPI) -- The O.C. alums Ben McKenzie and Autumn Reeser reunited over the weekend.
The 38-year-old actor and 36-year-old actress, who played love interests Ryan Atwood and Taylor Townsend on the Fox series, attended the "We All Play" fundraiser Sunday at the Zimmer Children's Museum in Los Angeles.
McKenzie was all smiles as he posed for a photo with Reeser, who attended the event with her two sons. The actress, who shares her children with ex-husband Jesse Warren, posted a picture of 5-year-old Finn and 3-year-old Dash on Instagram.
"My children discovered a wall of donuts, aka heaven. #zimmermuseum #weallplay #weallplay2017," she captioned the snapshot.
McKenzie and Reeser co-starred as Ryan and Taylor in Seasons 3 and 4 of The O.C. The actress discussed the characters' relationship and the prospect of a reunion in an interview with People's Choice in 2015.
"It was a slow progression between the characters," she said of the romance. "And I adore Ben, I loved working with him. We had a good working relationship, so it was a pleasure to get more screen time with him because I like him as a person."
"I will always love Taylor," the star added. "And I would be so curious to see where she's at in her 30s. I would love to [do a reunion]. I would be totally down for that."
These days, McKenzie portrays James Gordon on the Fox series Gotham, while Reeser plays Leslie Bellcamp on the E! drama The Arrangement.
