The 'Cannonball' girl band - individually known as Jesy Nelson, Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock - explained that they had planned to get a place together during their time on the show.
"Even if we hadn't won, we decided we were all going to move in together and keep going," Edwards told OK.
Nelson added: "We can't wait to get a flat together. I want us all to be together. I don't want a four-bedroom place. I love living in the same room!"
However, it was decided that there would be no place in the Little Mix flat for Pinnock's pet dog, after Nelson and Thirlwall expressed concern that the pooch would become a distraction.
"I love a good dog but we're going to be very busy and it's going to be hard looking after a dog," Thirlwall argued.
Little Mix have recently spoken of their determination to achieve international success.
