Miley was on Spanish television show "El Hormiguero" (The Anthill). It is a Spanish program with a live audience focusing on comedy, science, and politics.
I didn't post the videos here because they are mostly in Spanish, but there are lots of clips on YouTube. Check out Part 1 - Part 2 - Part 3 - Part 4 - Part 5.
