"Best of luck, Evanna. Hope you win!" author Rowling added.

Felton, who played Draco Malfoy in the eight Harry Potter films, said: "Despite all of our differences at Hogwarts, I want to wish you all the very best tonight. Keep making us all proud."

"I love you so so much, best of luck!," Katie Leung (Cho Chang) said.

"Bonnie here, your fellow Hogwarts alumni," Bonnie Wright (Ginny Weasley) added. "Wishing you all the best tonight Evanna and Keo."

James Phelps (George Weasley) and Matthew Lewis (Neville Longbottom) also sent good luck messages. "Bring it home," Lewis said.

Lynch and her dance partner Keo Motsepe's magical footwork earned them perfect tens for both their dances on Monday night's final, but they eventually lost out on the trophy to radio personality Bobby Bones.
