Britney Spears has topped ET's annual Hot List. The 27-year-old singer - who has achieved incredible success with comeback album 'Circus' - took the coveted number one spot in the list, made up of the stars who have received the most coverage and mentions on US TV show 'Entertainment Tonight' in the past year.
