Katie Price is said to have kept guests up all around the clock with her musical comeback.
The former glamour model, 41, put on an energetic vocal performance at the Klub Summit UK Garage Festival in Val Thorens, in France on Sunday.
It's claimed ahead of her hotly-anticipated musical gig, the businesswoman got in some last minute practice in the four walls of her hotel room earlier that night.
Her loud vocals were reported to have sparked outrage among her fellow guests after she had dinner alongside the holidaymakers at Fahrenheit Seven.
A source told The Sun : "We were sitting next to Katie at dinner in the Fahrenheit Seven that night, so when she started rehearsing in her room later, we recognised her voice.
"Honestly, the rehearsal sounded like someone was getting murdered in the room. She wasn’t hitting any of the notes and it was echoing all around the resort.
"At about 11.30pm, someone leaned out of the window and told her to, ‘Shut the f*** up’. But she ignored them. She had four goes at one song before ditching it. She then left to go to the festival."
The Mirror has approached Katie Price for further comment.
Later on Sunday, Katie played to a rewarding crowd at the Klub Summit UK Garage Festival.
The hitmaker shimmied in a sheer lace teddy which she paired with skintight leather trousers.
Having a history with pop music, the bankrupt star tried to revive her singing career as she joined the likes of the So Solid crew at the festival.
The mother-of-five was in her element as she performed with confidence and sassy appeal.
Her musical talents hark back to when she collaborated with her now ex Peter Andre on studio album A Whole New World.
But she failed to get the prime spot of representing the UK in the Eurovision competition.
Earlier in the month, the businesswoman declared she was 100% going to sing on UK television reality show The Voice next year.
She told the Loose Women panel: "I'm actually going to do The Voice next year."
Katie has also devised a scheme to give make-up tutorials at £80 per head around the country in an attempt to earn some cash.
