Bilson and Christensen 'dating again'

Rachel Bilson and Hayden Christensen have reportedly started dating again, after having called off their engagement in August.

The couple, who met on the set of Jumper in 2007 and became engaged in December 2008, announced their split earlier this year.

People reports that Christensen was seen leaving Bilson's Los Angeles home last week.

It had previously been suggested that the split had been down to the pressures of conducting a long-distance relationship, as Christensen is based in Canada.

A source told the magazine that the couple had reunited, saying: "They're dating again."
