The Scream actor was announced as one of the celebrity cast members for the upcoming 13th season of the ABC competition during Monday night's Bachelor Pad episode.
Speaking on Good Morning America today, he said: "I'm just learning the first [dance] and it's an unknown language to me!
"I've always wanted to know how to waltz. I'm learning the Viennese waltz and it's really hard and really takes a lot of little detail but I'm excited to learn it. I've always wanted to dance at a ball."
