Kristen Bell and Idina Menzel reunite to sing latest 'Frozen' hit

Frozen stars Kristen Bell and Idina Menzel reunited during The Wonderful World of Disney: Magical Holiday Celebration to sing "When We're Together." The song is from Frozen's newest featurette, Olaf's Frozen Adventure.

Before performing, the two were asked by Jesse Palmer, "What do you guys love about performing together?" Both performers agreed that they genuinely like each other, which makes performing together better. Bell also said, "Idina's a real professional musician so I know if I screw up she's got my back."

The two were flawless in their performance of the song, which literally ended on a high note with fireworks.

The rest of the show was also packed with wonderful performances from Jason Derulo, Ciara, and Hanson. But as the saying goes, they saved the best for last.
