R&B singer Mary J. Blige insulted her very professional band Saturday night during a Pre-Grammy Bash hosted by Clive Davis at the Beverly Hilton.

As the band struck up the number’s intro, she told the musicians to stop, waved her arms angrily and demanded: ‘Can we get the right music for Mary J Blige?’

She added: ‘Are we practicing still?’

The audience stared at her in disbelief as it is not considered the done thing to criticise your band  – all top of the line professionals – at such an event.

Those in attendance that witnessed the diva’s temper included Barbara Streisand, Usher, Bon Jovi, Joan Collins, Taylor Swift, Katy Perry, Maxwell, Fergie and the Kings of Leon.
