It's time to make the third annual PopSugar 100 List and this time we're mixing things up to make it even more interactive and fun. This year it's single-elimination tournament style with a bracket to help us narrow down to the perfect list. We chose 128 celebrities who we divided into four groups and then ranked from 1-32. The potential PopSugar 100-ers are then paired up in head-to-head matches, at which point you'll all vote on who had the bigger year.

Whoever wins will then proceed to the next round and so on until we have the Sweet 16, Elite 8, Final 4 right down to the single winner. The first round starts today and will last two weeks in which you can vote on each of the first 64 matchups — just click on any pair of names and work your way around the bracket! You can come back at any time and pick up where you left off.

After the round-one winners are determined, each sequential round will last one week coming to a winner at the beginning of June. As if the game wasn't addicting enough, we are giving away an amazingly hot, white Chanel bag to those who play.

You are entered to win with every round you complete — up to seven times the chances of winning! If you miss a round, don't worry, you can still enter to win multiple times. The winner of the almost $3,000 bag will be chosen randomly from the pool of users that completed each round and announced in June around when the new PopSugar 100 list is revealed. You must be logged in to your TeamSugar account in order for your entry to be counted. Log in or register here! Click here for all the rules.

Who will take home the top spot? Will it be Angelina Jolie or Brad Pitt again or will there be an upset this time around from one of the younger up-and-comers like Robert Pattinson. Plus, Jennifer Aniston did establish herself as a box-office magnet this year. Now, let's get round one started!
