Mel B pulled down the hem of her three-quarter dress before attempting the 'Gangnam Style' dance with Psy on Tuesday night, and now we know why!
Guy Sebastian has revealed that his fellow X Factor mentor was actually going commando.
Talk about tempting fate!
"People would have liked to have the view where we were in the judging panel — yes, it was 'scary'," Guy told The Daily Telegraph.
While she narrowly avoided the most disastrous wardrobe malfunction of all time, Guy revealed that Mel didn't get off scot free. Apparently, that sheer yellow dress gave away "a little bit too much information".
While you let that stew, check out our gallery of the other ladies whose wardrobe choices gave away "too much information".
UPDATE: Guy has revealed his comment was misconstrued when Mel confronted him on Twitter.
"Stop saying that! I did have underwear on brother!" Mel tweeted.
"Bahaha I actually never said that. I said lots of peeps would have liked that view but nothing about underwear! Funny though!" Guy replied.
