The Voice Australia coach Kelly Rowland isn't one to hold back when it comes to her opinions, but now The Voice viewers are switching off having had enough of the Destiny's Child singer's "huge ego".
WATCH: Boy George reignites feud with Kelly Rowland
Fans of the Channel Nine singing contest were quick to jump on Twitter to criticise 38-year-old Kelly during Sunday night's episode after she bent the rules for her contestant Denzel M Akuma and let him sing his own track.

"Kelly you think you're so smart breaking rules, but Australia has had enough of you and your huge ego," one annoyed fan shared.
"Kelly Rowland's behaviour on The Voice is nothing short of childish and pathetic. Take responsibility for your actions," another disgruntled viewer tweeted.
Fellow mentor Boy George, 58, soon jumped in to accuse Kelly of cheating in the way she structured the round.
The pair have almost come to blows before, and things soon got heated as the Culture Club singer didn't mince his words and verbally laid into Kelly in front of her contestants.
"People are breaking the rules and I'm just calling them out for being hypocrites," the British singer said.
After George asked Elsa Clement and Amanuel Clement what they thought about having to perform other artists' music rather than their own, and the non-plussed pair said they didn't mind, George almost lost it at them too.
"Step up guys - don't be compliant. That's not starting a revolution that's just agreeing with Kelly," he raged.
"She's completely wrong and that might mean you're going home."
At which point, Kelly jumped in, and hit back at her co-host, telling him to "stop attacking my artists".
Looks like this TV feud is set to run and run!
And The Voice dramas continue with Jack Vidgen, after the 22-year-old admitted he's broken down on several occasions as he's overwhelmed by the public support.
Talking to 9Honey Celebrity, Jack revealed that he keeps "bursting into tears randomly" because he has experienced "so much overwhelming love and kindness and positivity".
