A source says the split “was mutual” and that Phillippe, 36, and Seyfried, 25, “were never fully committed.” The couple met at Kate Hudson’s Halloween party last October.
“They were always on and off,” the source says. “They were always seeing other people.” Other people included the actor’s ex-girlfriend Alexis Knapp, who said Phillippe was the father of her baby (due this month).
The source says the split was amicable: “There’s no bad blood. They’re cool.”
