"Dancing With The Stars" season 20 got emotional as Zac Efron and Robert De Niro's "Dirty Grandpa" co-star Julianne Hough returned to the dance floor.
In 2007, the 15-year-old Hough won "Dancing With The Stars" season 4 with her partner speed skater Apolo Ohno. This made her the youngest professional dancer to win on the dancing contest.
Hough's return to the "Dancing With The Stars" dance floor is not the only things that made the recent episode emotional. In the pre-dance interviews, families of the four remaining contestants went on about how proud they were.
Moreover, Sharna Burgess's dancing partner Noad Galloway skipped his post-dance chat with Tom Bergeron's co-host Erin Andrews to propose to his girlfriend Jamie on air. Burgess and Galloway's paso doble was coached by judge Carrie Ann Inaba while Rumer Willis and Val Chmerkovskiy's ballet was coached by judge Bruno Tonioli.
Galloway and Burgess garnered a score of 36/40 + 30/40 while Willis and Chmerkovskiy scored 38/40 + 30/40. Both pairs Riker Lynch with Allison Holker and Nastia Liukin with Derek Hough/Sasha Farber scored 40/40 + 30/40.
Currently, Hough is filming the 2016 film "Dirty Grandpa," which is directed by Dan Mazer and written by John Phillips.
