Mel B danced along with Psy to 'Gangnam Style' on The X Factor Australia.
The public had a vote on which judge should dance along with Psy to his No 1 smash hit, 'Gangnam Style'.
Having received the most amount of public votes, the former Spice Girl, reluctantly got to her feet and took to the stage.
"My daughter will kill me if I don’t do this," Mel B said.
The X Factor judge then enthusiastically launched into a mini-dance routine with Psy, amid shouts and cheers from the studio audience.
Mel B stated after the performance: "My daughter sai she'd cook me breakfast in bed on Friday… I thought my legs were about to snap!"
'Gangnam Style' has been a chart topper for weeks now and is No 1 in the ARIA Singles Chart in Australia.
