So if the rumours are true, Jesy Nelson, Leigh-Anna Pinnock and Jade Thirlwall will be bridesmaids, while the other One Direction boys - Harry Styles, Liam Payne, Niall Horan and Louis Tomlinson - will be ushers.
"I don't want to be engaged for 50 years. We'll get there soon," she said.
"I actually wanted to have quite a small wedding, but then all the girls in my family are desperate to come and would like to be bridesmaids too.
"I realise my wedding is every journalist's dream. It's going to be like the movie 27 Dresses where the bride has like a billion bridesmaids."
The couple announced their engagement back in August when Perrie arrived at the One Direction: This Is Us premier showing off a sparkling diamond ring.
Bring on the big day, we say! It will be former X Factor bands galore!
P.S. Did you see the girls in their Legally Blonde get-up for Wonderland magazine. It's pretty fab.
