Big Brother 9 came to an end on Friday, but I can't get the housemates out of my head. The big story of this year's series for me was the number of couples. Lisa and Mario went in as a couple, and came out engaged, while Rex's girlfriend Nicole was a surprise new housemate late on in the show's run. Then there were the in-house romances, from Dale and Jen (already over) to Bex and Luke. I want to know your thoughts on all these pairings, so tell me: who's your favourite BB9 couple?
