The former Spice Girl put her tongue firmly in cheek when she attended Jonathan Ross' annual fancy dress frightfest... dressed as herself!
Mel, 39, arrived at the star-studded party squeezed into a leopard-print catsuit reminiscent of ones she famously wore during her time in the Spice Girls.
The low-cut bodysuit flashed plenty of cleavage and left little to the imagination - just as well the fitness bunny has a toned body to die for!
Wearing a big curly wig, pussycat ears and supersized platform trainers, Mel - who has admitted that she kept all her outfits from the girl band - proved that the years have been kind to her since the five-piece split.
Husband Stephen Belafonte and kids Madison Brown Belafonte, Phoenix Gulzar and Angel Murphy Brown all looked the part, too.
While Mel B might have stolen the limelight just a tad in her jawdropping outfit, lots of other famous faces got into the Halloween spirit to attend the chat show host's famous annual shindig in his Hampstead home.
Celebrity Juice star Leigh Francis looked scarily realistic as film ghoul Beetlejuice, while notorious funny man Alan Carr dressed as US pianist and singer Liberace.
Top marks also go to Kate Moss who showed her sense of humour by dressing as fellow catwalk model Cara Delevingne in round glasses and beanie hat.
So convincing was her disguise, we had to do a double take!
