The flame between Joshua Jackson and Diane Kruger still burns strong. The couple, who have been dating for six years, were spotted at Katsuya in Hollywood Thursday night. Spies say they sat across from one another and were “constantly holding hands or caressing each other’s faces.” The lovebirds weren’t the only ones out for sushi with their mates. Rocker Fred Durst also came in with his wife and sat at a separate table near Dave Navarro, who dined with a lady friend.
