Ariana Grande may have taken her Mariah Carey copying a little too far...

Lambs fans are fuming at Mariah Carey impersonator Ariana Grande. Apparently, she has a bonus cut on her upcoming new album 'My Everything' and it sounds exactly like Mariah's 'I've Been Thinking About You' from her classic 1993 album 'Music Box.' 

Of course it could be a cover tribute or at least I hope so. Because if not, Mariah could easily sue Ariana's camp for copyright infringement.

IF this is a cover (and most likely it is), she's doing herself no favours against those excessive accusations that she's trying to swaggerjack Mariah's sound and career. The original song was written AND composed by Mariah, alongside Robert Clivillés and David Cole.
