Let's be real — we'll never be ready to let Frozen go. On Monday, Kristen Bell — who voices Princess Anna in the 2013 Disney blockbuster — continued to stir our Frozen mania as she gave us her best reprisal of the movie's hit track "Let It Go" along with a surprise reveal that's giving us some serious feels.

In a sweet clip shared to Instagram, the Bad Moms star can be seen mouthing along to the tune's lyrics, "The wind is howling like this swirling storm inside / Couldn't keep it in / Heaven knows I've tried…" before her onscreen sister Idina Menzel appears from the background just in time to belt out the soaring chorus.

"SISTERS. (I [heart emoji] u @idinamenzel," the mom-of-two captioned the video, which shows the Rent star break down in laughter during her spotlight moment.

SISTERS. (I ❤️ u @idinamenzel)

Considering that Bell has been keeping the Frozen love alive and well with her recent Halloween costume and the fact that a yet-untitled sequel is in the works for 2019, we're officially counting down the days until these "sisters" reunite on-screen.
