Katy Perry has had an amazing year.

The sultry pop star—and former Maxim Hot 100 champ—dropped "Rise," a new track that's being used as an anthem in this year's Presidential election, went door-to-door to campaign for Hillary Clinton, and even found the time to paddleboard with a very nude Orlando Bloom.

While we're still waiting for her fifth album (and a suitable song response to her salty (and single) frenemy Taylor Swift), the California Girl's big 3-3 is a perfect excuse to relive the reason we're obsessed in the first place.

Below, take a peek at her sexiest shots from Katy's previous Maxim shoot. Katy, you haven't aged one bit!
