The actors took in day three of the tennis tournament at USTA Billie Jean King National Tennis Center. The day’s matches included Serena Williams, Sloane Stephens and Andy Murray. Ella sat between her parents as they took in the action, with all three sporting bright smiles on their faces.
Stiller, 52, and Taylor, 47, announced their separation after 17 years of marriage in May 2017. The two share Ella and her younger brother Quinlin, 13. They were seen together in public last month for the first time since their split.
A source told PEOPLE that “the pair remain friendly and devoted parents to their kids.”
Putting the kids first has been a priority for the stars from the beginning, with both mentioning it in their joint statement about the split.
“With tremendous love and respect for each other, and the 18 years we spent together as a couple, we have made the decision to separate,” Stiller and Taylor said. “Our priority will continue to be raising our children as devoted parents and the closest of friends. We kindly ask that the media respect our privacy at this time.”

A source told PEOPLE at the time that Stiller’s hectic work schedule helped contribute to the breakup.
“It gets hard — he has a very busy Hollywood career, and she’s been very focused on being a mom,” the insider said.
“They are a very loving family,” added the source, who didn’t expect a messy uncoupling from the pair. “[Christine] and Ben respect each other and will do anything to make sure their kids are happy.”
