It’s Diane Kruger!
Most recently, Kruger starred in the 2011 Liam Neeson film 'Unknown' alongside January Jones. She has several upcoming features, including 'National Treasure 3,' which is due to release in 2013.
Kruger has been dating Joshua Jackson since 2006, and appeared on his FOX show, 'Fringe' in 2010, as a guest star. Oh Pacey, we're still confused about how you bag all the hot broads, but kudos, mate.
