Mel and JT got a little more than they bargained for during the Quick Fire Five with Nadia Lim earlier this week.
After answering questions about her favourite car karaoke tunes, and the last lie that she told, Mel asked a question about embarrassing outfits.

"What was I in for my hen's do, what did they put me in?" Nadia asked.
"Oh, they made me go in my birthday suit! But let's not talk about that..." she added.
Before Nadia could sweep that story under the rug, Mel questioned her further - and the results were hilarious!
