Britney Spears went through a rollercoaster ride last year. Drug problems, alcohol abuse and divorce had the pop diva smothered until she put her foot down and decided to redeem herself. She is now on the way to the top again, but come what may, she has always been in the news. And that has made her the hottest celebrity on the planet, according to a survey conducted by USA Today's annual Celebrity Heat Index which measures how much exposure and media attention a star gets in print and online.

The list has been topped by Britney; second in line is Angelina Jolie, whose life and romance with actor Brad Pitt makes headlines for even the simplest of reasons; Jennifer Aniston comes third and Brad Pitt follows her at fourth place.
