Will Cast Shake-Ups Hurt TV's Biggest Dance Contests?
Derek Hough is leaving "Dancing with the Stars," and Mary Murphy won't return to "So You Think You Can Dance." How will this affect the shows?By Katherine Biek | January 13, 2015
Major shake-ups are heading for the dance floors of the two largest reality dance-competition shows on television.
Professional dancer Derek Hough announced Tuesday he's leaving the "Dancing with the Stars" ballroom for the show's 20th season to perform at Radio City Music Hall this spring.
This news came after Hough cryptically posted a photo of the Brooklyn Bridge with the caption "A new chapter is coming" on his Instagram account Monday.
