The year of the cougar.
Our number 1 hook-up of 2011 has to be the wonderful union that is Harry Styles and Louis Tomlinson, better known as Larry Stylinson. The beautiful relationship grew from strength to strength since that fateful day were put together on X Factor, and the boys took their commitment to the next level when they moved in together earlier this year.
Girls like Eleanor Calder and Caroline Flack may come and go but this is one bond that will never break.
What do you think? Did any of these relationships shock you? Of the ones who are still together, whose relationship do you think will last the longest?
