We don't know about you, but we loved the judges' make-up almost as much as Saturday night's show (11 October) and when we found out Mel was wearing a lipgloss that costs less than a fiver, we loved hers even more!
Saturday night was the first of the live shows and eventually saw groups Blonde Electra and Overload Generation as the first contestants to be voted off on Sunday.
Mel, who is mentoring the boys Jake Quickenden, Paul Akister, Andrea Faustini and wildcard Jack Walton looked absolutely stunning in a floor-length, white Alexander McQueen dress with a black bow around the neckline.
She also rocked some classic, black Christian Louboutin heels with matching black, vampy nails and slicked back hair.
But in contrast, her make-up was soft, warm and gorgeously glowing...
Mel's look was created by celebrity make-up artist Adam Burrell, who's also painted the faces of Little Mix, Sarah Harding, Cher Lloyd and The Saturdays, as well as working on The X Factor for many years.
Working with a bronze palette on Mel's eyes, cheeks and lips, Adam created a super-glam look that totally worked with her hair to create a sexy, feminine look.
And while her outfit would never make it into our wardrobes (unless we won the lottery pretty sharpish!), her lipgloss we can totally copy as it was none other than Barry M Lip Gloss in Toffee, £4.59, barrym.com.
Wear yours with smoky bronze eyes, plenty of false lashes and a slightly shimmery bronzer on your cheeks for a similar, Mel B finish.
ps: We also love Bourjos Effet 3D Lipgloss in Beige Elastic, £7.99, boots.com and Maybelline Colour Show Elixir Lipgloss in Nude, £6.99, superdrug.com.
