Before there was Hannah Montana, there was Lizzie McGuire, and right from the start, you couldn't help but wish that Hilary Duff  was your BFF 4ever. Lizzie McGuire hit the small screen in 2001, and Duff's lovable character had all the sass and style of one very cool tween. The show ended in 2004, and since then, Duff's Hollywood résumé has been packed with films. Although she's made some TV appearances on shows like Gossip Girl, Community, and Two and a Half Men, she hasn't been part of a regular TV cast since her Disney days. That's about to change, though, because she's starring in Younger, a TV Land series that's based on Pamela Redmond Satran's novel  by the same name.
The new show follows Liza (Sutton Foster), a 40-year-old single mom who gets a makeover from her best friend (Debi Mazar) and tries to pass herself off as a 26-year-old. When Liza dives back into the working world, she befriends a coworker named Kelsey, played by Duff. To celebrate Duff's return to TV, we're looking back on why Lizzie McGuire is the coolest.

Lizzie's so young and cute — Duff was only 13 when the show started
Plus, she's a great friend with the friendship bracelets to prove it.
She travels with a very cool pack.
Like, very cool.
They keep up via landline phones, obviously.
And let's not forget her awesome style.
She isn't afraid of a bold accessory.
Or a sheer bandanna.
Or colorful hair.
Or some crimping.
Yep, even the cartoon version of her looks fabulous.
Meanwhile, she's got a little sass.
Nobody does a better "WTF" face.
Seriously, it's perfect.
So is her "talk to the hand" move.
And her fake smile.
And her "sorry I'm not sorry" move.
She isn't perfect, which makes her all the more likable.
She loves love.
And wins over pop stars.
But she definitely has her tough days.
And plenty of insecurities, just like the rest of us.
She knows that relationships can be hard.
And that you don't always get what you what.
She knows that friendships can be tough, too.
But she knows how important true friends are.
And how important dance parties are, too.
She accepts herself for who she is.
And she has some pretty healthy self confidence.
At the end of the day, Lizzie — er, Hilary — is crazy talented.
And, yes, it's true — she made us love Disney.
We'll definitely be tuning in for her new show!
