Rachel Bilson and Hayden Christensen could be possibly heading or are already in splitsville.

The couple, who co-starred in the film "Jumper", is said to be "on a break", which is more or less an indication that they've either split up, or are headed in that direction.

Sources told US Magazine that Bilson and Christensen, who were engaged in February 2009, are definitely "on a break".

It was odd that Bilson was alone during the Take No Prisoners event in LA this week.

When she was asked about when her wedding will be, she said, "No, no plans," as she pointed to her ring-less finger.

"No nothing."

According to sources close to the couple, they are "taking about a month off" and will reexamine their relationship before they make a decision if they are to stay together.

They decided to start their break two weeks ago.
