Ryan Phillippe single again....?

Actor Ryan Phillippe is apparently single again after reports of his break-up with girlfriend Amanda Seyfried surfaced.

Phillippe and the "Mamma Mia" star, who first met at friend Kate Hudson's Halloween bash last year, have ended their seven-month romance, reports dailystar.

"It was mutual. They were never fully committed. They were always on and off. There's no bad blood. They're cool," said a source.

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.
