Ryan Phillippe and Amanda Seyfried have ended their relationship again.

The couple - who briefly split in February - are said to have mutually agreed to call time on their seven-month romance but plan to stay friends.

A source said: "It was mutual. They were never fully committed.

"There's no bad blood. They're cool."

According to friends, 36-year-old Ryan - whose former lover Alexis Knapp is due to give birth to what she claims is his baby later this month - and Amanda, 25, were never serious about their relationship and continued to date other people.

The source added to reporter: "They were always on and off. They were always seeing other people."

News of the split comes weeks after Amanda spoke of her desire to have children.

She said: "I want children! My publicist now has two kids - I love her, so I like to think I'm an auntie to her kids. I can't wait to have my own! I think it's really exciting to know that I want them. Knock on wood, I hope I'm fertile, but I've never got pregnant before."

Ryan has daughter Ava, 11, and son Deacon, seven, with ex-wife Reese Witherspoon.
