Christensen proposed to Bilson over Christmas

Actor Hayden Christensen reportedly made Rachel Bilson's Christmas holidays extra special by asking the actress to marry him.

The couple, who met on the set of movie 'Jumper' in 2006, became engaged in December, while staying at Christensen's family home in Vancouver, Canada, according to reports.

A source tells America's Star magazine: "He gave her a diamond ring, and she accepted without hesitation. Everyone's so excited. Hayden's family adores Rachel - his sisters even helped him pick out the ring."

The insider alleges their nuptials are likely to take place in Canada because Los Angeles-born Bilson "loves it there", adding: "She's a down-to-earth girl - and she's brought out the best in Hayden."

A wedding date has yet to be set.

Bilson's representative has refused to confirm or deny the reports, stating: "I don't comment on my clients' personal lives."
