As happy as we are the temperatures are finally picking up outside, we're not above admitting it: We've had Frozen fever ever since the 2013 movie release.

That's why it's a good thing that Frozen Fever hits theaters tomorrow, as a prelude to the new Cinderella movie. If you plan on catching the full-length Cinderella, you'll get a short glimpse at what's going on with our favorite characters from Frozen.

If that one-day wait is too much for you, here's something that'll make your day: "Making Today a Perfect Day," a new song from the reunion, has debuted early and is available for purchase on iTunes.

Sung by the gang from the original Disney movie — including Olaf, Kristoff and of course, Elsa and Anna — "Making Today a Perfect Day" is all about setting up Anna's birthday celebration.

Frozen Fever is just seven minutes long and stars Frozen's original cast members Kristen Bell, Idina Menzel, Jonathan Groff and Josh Gad. The story centers on Princess Anna's birthday. Despite Elsa's best attempts to make the day a "perfect day," her powers start to act up when she catches a cold that threatens to ruin the day for everyone.

We are so excited to catch the original Frozen cast back in action and hope the seven-minute trip to Arendelle shows us that Anna, Elsa and the rest of the gang have all found happiness.
