Speaking to DailyMail.com at the Daily Front Row Fashion Media Awards shortly before flying to Milan, the Making The Cut star stated: “I drive myself crazy every time about my Halloween costume because I don’t want to do things that might to be expected .

“I think what I’m doing this year is one of the most unexpected… that no one would think about. People will keep saying “Whattttt?”

As for a hint as to what she’d be wearing, the mum of four simply teased, “I’ll be very claustrophobic in my outfit…”
