Mariah Carey rehearsal audio leaked + Billboard Music Award performance confirmed...

TMZ are well known for throwing shade at Mariah Carey, so for them to give her some vocal props is quite a turn around.

The celebrity rag you just love to hate has leaked audio from her Vegas rehearsals which kicks off later tonight.

She's hitting notes and her voice does sound in better shape. But there's also the possibility she could be heavily aided by a backing track (Mimi's best friend apparently). We shall see though. 

In related news, Mariah will take to the stage at the 2015 Billboard Music Awards for the first time in 17 years. Tune in on May 17th!
