Amanda, 49, donned a black wraparound dress which resembled an elegant dressing robe as she posed for a video in the Heart FM offices on Wednesday.
The blonde bombshell showed off a daring amount of leg as she spun herself on an office chair, risking a wardrobe malfunction as the dress fell open.
Allowing the skirt to gape open to either side of her legs, Amanda's long toned pins stole the show as she crossed her legs to protect her modesty.
She looked seriously glamorous in the long-sleeved dress, which featured a plunging neckline and a cinched in belt, as she showed off her slim frame to the camera.
Letting her hair fall around her shoulders in loose waves, Amanda flaunted her natural beauty as she kept her make-up simple but elegant.
She finished the look off with black strapped heels, sending her fans wild with the racy video.
This isn't the first elegant outfit Amanda has worn this week, as she put on an eye-popping display in several dresses while leaving the Heart offices in London.
Only yesterday, she ditched her underwear underneath a figure-hugging sunshine yellow dress while strutting her stuff through the office.
The halter neck dress clung to her curves as she turned her workplace into a catwalk, leaving her fans hot under the collar.
Amanda told her fans she'd opted for the bright dress as she "had a feeling today's the last day of sunshine".
It didn't take long for the compliments to come pouring in for the mum-of-two, as fans gushed over her show-stopping display.
One posted: "You look incredible."
Another added: "LOOKING GORGEOUS AS ALWAYS."
A third chipped in: "Oh my the dress was so cute i so love it& so are you."
A fourth wrote: "Beautiful as ever."
BGT continues on Saturday at 8pm on ITV.
