Britney Spears Looked Like This

Which you obviously already know if you've been a die-hard Britney fan for decades.

And Oops! . . . I Did It Again Shattered Records

Britney's second album debuted at the top of the US Billboard 200, selling 1.3 million copies in its first week. To this day, no other female artist has topped this first-week sale number.

But Eminem Blew Everything Out of the Water

Eminem's album The Marshall Mathers LP was an even crazier success than Britney's, selling 1.7 million copies in the first week. That's the third fastest selling album in history.

Not to be outdone, No Strings Attached outperformed both Oops! . . . I Did It Again and The Marshall Mathers LP by selling more than 2.4 million copies, the most albums ever sold in the first week.

Leonardo DiCaprio Looked Like This

Not quite Titanic, but not quite The Great Gatsby either.

Jennifer Lopez Wore Her Infamous Grammys Dress

The dress in question was pretty scandalous for 2000, but nothing compared to some of the dresses of the past year. Remember Rihanna's dress at the CFDAs?!

Angelina Jolie and Billy Bob Thornton Got Hitched

. . . And Brad Pitt and Jennifer Aniston Tied the Knot

It's just so weird that it all happened in one year.

Beyoncé Looked Like This

Once a queen, always a queen.

The Music Video For "Say My Name" Dropped

Back when Destiny's Child was still killin' it. They wouldn't officially disband until 2005, but Beyoncé's solo debut, Dangerously in Love, came out in 2003.

Boy Meets World Ended

It marked the end of a Disney era. And the end of an era in general.
