LISTEN: Mariah Carey’s Vegas Rehearsal Proves She Can Still Sing

Mariah to "Infinity"
Is this new song about Mimi's ex?

Say what you will about Mariah Carey and her vocal hiccups of the past, but dearest Mimi’s still got it.

Consider this audio of her rehearsal in Las Vegas earlier this week, ahead of her Caesar’s Palace residency:

According to TMZ, Carey delivered all the notes (including the mighty high ones) for more than an hour at the dress rehearsal inside The Colosseum. And yes, that’s really her singing every bit of “Emotions.”

All week long, the Elusive Chanteuse has been sharing snaps from rehearsal on Instagram:

The band is ready for our dress rehearsal! @davidkorins

In even more exciting Mimi news, it was just announced that the 45-year-old superstar will perform at this year’s Billboard Music Awards.

Carey, who has 14 BBMAs to her name, hasn’t performed on the Billboard stage since 1998. Remember 1998?

We still believe, Mariah.

Mariah #1 to Infinity kicks off tonight (May 6, 2015).
