Contestant James Van Der Beek got a blast from his Dawson's Creek past when his on-screen parents cheered him on from the audience.
To have John Wesley Shipp and Mary-Margaret [Humes] here, who played my mom and dad on Dawson's Creek, sitting together," Van Der Beek told ET's Keltie Knight after the show.
After Van Der Beek's performance, the two stars joined him on the dance floor for a reunion pic -- their first in 18 years!
Van Der Beek and his partner, Emma Slater, had a top performing night, scoring two nines and one eight from the judges.
We do it for us, we do it for the audience, we do it to circulate that energy, but to get a nice score at the end is fun," Van Der Beek told ET.
