“So, I have no idea it was such a surprise for me,” the singer admitted.
“Heather Small and Will Young [being unveiled] and all these people I have interviewed over the years, it’s just weird.”
On Saturday, Mushroom, Robobunny and Panda will perform for the last time.
After weeks of guessing, the three celebrities will be exposed, but only one will be crowned the winner.
The Masked Singer final airs on Saturday at 7pm on ITV.
