"Stacy called it quits. She wants to have children and a family someday. She knows where George stands on that," a source told People. "They talked and they quietly stopped being a couple several weeks ago."
"They talk every day. They were friends before they started dating and they'll be friends after. It was a friendly [breakup]," the source said.
News of the split comes after months of speculation over the couple's relationship status as they have been spending a lot of time apart. They were last photographed together in March.
