The Top 20 of So You Think You Can Dance's season four have been chosen. Our thanks to Kristin from E! Online for this glimpse at some of the dancers...

• According to finalist Marquis Cunningham: "They have forewarned us that there are going to be several new genres in the hat that they haven't shown the past three seasons."

• The top 20's first group dance will be choreographed by legend-in-the-making Wade Robson. Many of the contestants have admitted that Robson is choreographer with whom they'd most like to work.

• Jamie Bayard (pictured) is a scion of the Schwimmer dance dynasty. He's not biologically related, but he was the dance partner of Lacey Schwimmer for four years; they won two U.S. Swing Dance championships together.

• Chelsie Hightower went to high school with season-two star Allison Holker; Katee Shean grew up in the same town as season-one finalists Nick Lazzarini and Melody Lacayanga; and Matt Dorame and Thayne Jasperson study at the same studio.
