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 U.S. TV show "Entertainment Tonight" in the past year.

An ET writer explained: "From a historical election to surprising splits, sizzling romances and major comebacks, 2008 was a remarkable year for celebrity news." Britney - who has got her life back on track following her public breakdown, in which she shaved her head and lost custody of her two sons to ex-husband Kevin Federline - was followed on the list by US TV talk show host Oprah Winfrey.
