The 37-year-old judge - who has featured on the panel since 2012 - was hoping to perform her new track 'Stop' during the show on Saturday (28.05.16) in a bid to relaunch her pop career but producers have reportedly turned her down after she sparked uproar earlier this week over "racist" remarks.

A source told The Sun newspaper: "Alesha is disappointed but appreciates she can't complain too loudly.

"She knows how fortunate she is being on a show of 'BGT's size so would never want to put that at risk."

The brunette beauty came under fire, with some fans claiming she should be sacked, on Wednesday night (25.05.16) when she referred to Vox Fortura as "four sexy chocolate men" following their impressive performance in the semi-final heat.

She said at the time: "Four sexy chocolate men, with amazing voices, polished to perfection, that was sensational."

However, the quartet - which is comprised of two English men and two black Americans - were quick to jump to Alesha's defence after social networking sites blew up with uproar.

The group wrote to Alesha on Twitter: "If you think we are 'four beautiful chocolate men' can't get any better than that (sic)."

Vox Fortura were later dropped from the competition after losing out to the dance act Balance Unity and Beau Dermott.

The 'Britain's Got Talent' final will hit screens this weekend.
