Lauren Conrad Is Still BFFs With The Original "Laguna Beach" Cast Members

    Celebrate, indeed!

    Back in 2004, the world was introduced to a group of teenagers who would unknowingly change all of our lives in a big way.

    That's when we met Trey...

    ...Dieter...

    ...and of course LC.

    They've all been friends for quite some time.

    And have adorably stayed friends over the years, through it all.

    Yesterday, Lauren Conrad's party for her latest book, Celebrate, was no exception. Guess who came through?

    TREY AND DIETER, like the amazing BFFs they are!

    D'awwwww.

    Aren't these guys just as cute as they were back in high school?

    Good friends really do last a lifetime.

    CHEERS TO FRIENDSHIP!
