A source tells Us Weekly, "It was mutual. They were never fully committed. They were always on and off... There's no bad blood. They're cool."
The duo's relationship first hit a rough patch in March (11) when reports surfaced that Phillippe had fathered an unborn baby with his ex-girlfriend, model Alexis Knapp, who is due to give birth later this month (Jun11).
Representatives for Phillippe and Seyfried had not commented on the report as WENN went to press.
