Actor Ryan Phillippe is single again after splitting from his girlfriend Amanda Seyfried, according to a report.

Phillippe and the Mamma Mia! star, who first met at pal Kate Hudson's Halloween bash last year, have reportedly ended their seven-month romance.

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 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.

Representatives for Phillippe and Seyfried had not commented on the report as WENN went to press.
