Joshua Jackson and Diane Kruger are ready to have children. The couple - who have been in a relationship since 2006 - are "working on" starting a family, the actor has admitted.

"Kids are one of those things that kind of happen, aren't they? Certainly we're working on it if that's what you're asking," Joshua said when asked if they plan to have children.

Both Joshua and Diane - who was previously married to Guillaume Canet for five years from 2001 - have previously insisted they have no desire to tie the knot, and though it is still not "important" for them to make their union official, they won't rule it out completely.

Earlier this year, Joshua, 33, sparked engagement speculation after he won a $45,000 necklace at auction and was quoted as announcing it to be an "engagement gift" for the 35-year-old blonde beauty and the Fringe star joked the purchase was a "horrible mistake" because of the rumors it sparked: "I made a horrible mistake at an auction by raising my hand when I shouldn't have, and it started a bunch of rumors that were very, very costly. We're not engaged."
