Rachel Bilson and Hayden Christensen reunite for family day out

Actress Rachel Bilson reunited with her ex-boyfriend Hayden Christensen on Sunday (15Oct17) to spend time together as a family for the sake of their young daughter.

The stars reportedly called time on their romance last month (Sep17) after almost a decade together, but it appears they are doing their best to co-parent little Briar Rose, who will turn three at the end of October (17).

The exes were spotted taking their only child to the PAW Patrol Live show at the Dolby Theater in Hollywood over the weekend.

"They seemed perfectly civil, but not romantic or affectionate in any way," an onlooker told People.com.

Rachel and Hayden have yet to comment on their break-up, but they are both known for keeping their personal lives private.

They met on set of their 2008 film Jumper and became engaged by the end of that year, only to call off their plans to wed in August, 2010.

They reconciled three months later and in October, 2014, Bilson gave birth to Briar Rose.
