New York: Amanda Seyfried and Ryan Philippe have split after three months of dating.
The 25-year-old actress and Phillippe, who was previously married to `Legally Blonde` star Reese Witherspoon, mutually decided to part ways, reported Us magazine online.
"They are not dating anymore. And it`s not a big deal for either of them," said a source close to the former couple.
When they first started dating, the couple wanted a long-term relationship but the chemistry fizzled out as they did not have a lot in common.
"At one point, there was a chance it would develop into something more serious, but it never did. They are just very different people," added the source.
And Phillipe, 35, has already moved on as he was spotted chatting up popstar Rihanna during a party in Los Angeles.
"He said something to the effect of, `What are you doing tonight?`," one of the onlookers told the magazine.
