The Big Brother twins may not have won the show - coming second to Brian Belo - but Sam and Amanda have been busy working on new projects.The girls recently made their mark on the fashion world, modelling for Naomi Campbell.They said: "Naomi Campbell asked for Jamelia to do the catwalk with her and then our agent asked if we could go on and they said they don't book Big Brother contestants."Then they rang back the next day asking for the twins to do it, so we got to do it and meet top supermodels and celebrities."And it looks like Samanda have already made their fortunes, deciding to splash out on their family."We went to tell our mum and dad how we had decided to buy their house because they have done loads for us to get on Big Brother, especially our mum who helped loads and loads and loads," said the twins.The sisters have even recorded a cover of Aqua's hit Barbie Girl and are hoping they can hit the number one spot.© Independent Television News Limited 2007.
