The 34-year-old 'Poison' singer donned the jagged hemmed mini dress with a pair of towering white heels as she arrived at the LG Arena with fellow judges Sharon Osbourne, Louis Walsh and Gary Barlow.
Osbourne wore a cobalt blue leather jacket over a black maxi dress, while Barlow looked summery in a short-sleeved blue shirt and grey trousers.
Walsh arrived in a blue blazer and shirt tucked into his jeans.
Scherzinger confessed to photographers and fans congregating outside the city's arena: "I can't pronounce Birmingham."
They responded with "Birm-ing-ham", to which she repeated: "Ahhhh, Birmingham."
Meanwhile, Barlow tweeted: "Here we come Birmingham ! #XFactor
"To all contestants, if you really want this..... Show us ! #XFactor"
Auditions kicked off in Glasgow last week (June 4), which saw a delighted Sharon posing with two shirtless men wearing kilts at the Hilton Glasgow Grosvenor Hotel.
The X Factor, which returns to ITV this autumn, will also hold auditions in Manchester, London and Cardiff.
