Hollywood stars Rachel Bilson and Hayden Christensen have reportedly rekindled their romance - three months after calling off their engagement.

The couple became engaged in December 2008 but parted ways in August, amid reports they were struggling to maintain a long-distance relationship, with the former "O.C." star living in California and the "Star Wars" hunk in his native Canada.

Now the stars, who met on the set of the 2007 sci-fi movie "Jumper," are said to be giving their romance another try.

A source tells People.com, "They're dating again."
