It’s hard to believe, but it’s been 18 years since the year 2000 – where has the time gone…

And with the threat of Y2K no longer looming over our heads, we figured now is as good a time as ever to look back on the noughties.

It was an interesting decade, filled with questionable hairstyles, and even more questionable fashion.

It was the decade that gave us Paris Hilton, cropped tops, sparkles and the colour pink – so much pink.

And even thought it may feel like just yesterday, we can honestly say no one misses the tiger streaks that dominated everyone’s hair. Some things are better left in the past.

It wasn’t all bad though – the noughties also gave us iconic couples like Brad Pitt and Jennifer Aniston, Jennifer Lopez and Ben Affleck, and Ryan Gosling and Rachel McAdams.

Here are 30 photos that are so noughties, you’ll be tempted to go out and frost your tips. But please don’t.

What a time to be alive.

1. Ashley Tisdale & Zac Efron

Just in case you’d forgotten, Zac Efron first rose to fame in a little Disney movie calledHigh School Musical.

The film also starred Ashley Tisdale and Vanessa Hudgens, and was released in 2006.

Yep, it’s hard to believe, but Zac has only been on our radar for 12 years…

Also, he wore Justin Bieber’s haircut better than Justin Bieber. Just sayin’.

2. Britney Spears & Justin Timberlake

If the noughties were a teen movie, Justin Timberlake and Britney Spears would have been prom king and queen.

Their relationship was the stuff of teen dreams... right up until they split in 2002.

Their break up hit us all hard, with Justin even reportedly writing his hit single, "Cry Me A River", about the split.

Still, at least we'll always have their matching denim ensembles to look back on.

3. Cameron Diaz & Drew Barrymore

Cameron Diaz and Drew Barrymore were the BFFs we all wanted.

They were fun, cool, and they always seemed to have each other's backs.

After meeting on the set ofCharlie's Angelsin 2000, these two pretty much became inseparable from day one (sorry, Lucy Liu).

Also, we'd be lying if we said we didn't miss seeing them out together - #originalfriendshipgoals.

4. Gwen Stefani

We don't know what fountain of youth Gwen Stefani has been drinking from, but that girl hasn't aged a day.

After first rising to fame in the '90s with her band, No Doubt, Gwen went out on her own in 2004 and released her debut solo album,Love. Angel. Music. Baby.

And if you haven't gotten down to "Hollaback Girl" at least once in your life, you're just lying.

While she's kept her trademark bleached blonde hair and red lipstick, we're not sorry to say goodbye to the mesh cropped tops.

5. Hilary Duff & Amanda Bynes

Hilary Duff and Amanda Bynes were both ruling teen queens in the noughties.

Hilary was famous for her starring role inLizzie McGuire, which ran from 2001 until 2004, while Amanda had her own comedy skit show,The Amanda Show, which ran from 1999 until 2002.

In fact, they were so popular, you would have been hard-pressed to find a teen magazine cover that didn't feature their beaming faces looking out at you.

Since then, Hilary has gone on to find success with a new TV series,Younger, while Amanda... has had a bit of a rough time in recent years, but seems to finally getting her life back on track.

6. Destiny's Child

Even in the noughties, it was evident Beyonce was therealstar of Destiny's Child, but we'll always have a soft spot for this all-girl group.

After finally calling it a day in 2006, the girls - Beyonce, Kelly Rowland and Michelle Williams - all embarked on solo careers with varying levels of success.

Still, nobody wore matching over-the-top costumes quite like these three.

Apparently most of the group's early costumes were made by Tina Knowles, and if that doesn't scream "dance mum", we don't know what does.

7. Jennifer Aniston & Brad Pitt

Ahhh, Jennifer Aniston and Brad Pitt - the love story that just won't quit.

People couldn't get enough of this noughties romance, and in 2018, there's still a whole legion of fans who are silently willing them to get back together.

After apparently meeting through their publicists, the pair were married for five glorious years from 2000 until 2005... when Brad dramatically dumped Jen for Angelina Jolie.

And we all saw how that worked out.

8. Britney Spears & Madonna

It might seem like no big deal now, but in 2003, Britney Spears making out onstage with Madonna at theMTV Video Music Awardswashugenews.

After performing a medley alongside Brit and Christina Aguilera, Madonna finished up her song, "Hollywood", by planting kisses on both girls - but it was her kiss with Britney that really raised eyebrows.

Maybe it was because Justin Timberlake - who had only recently split from Britney - was sitting in the audience looking seriously p*ssed off.

But it probably had more to do with the fact that up until that moment, Britney had been America's Sweetheart with a squeaky clean reputation.

9.Charlie's Angels

Based on the '70s TV show of the same name,Charlie's Angelswasthemovie franchise of the noughties.

Yep, before superheroes were a thing, we were all watching Cameron Diaz, Drew Barrymore and Lucy Liu kick butt onscreen as undercover private investigators working for the elusive "Charlie" - no special powers necessary.

The first film came out in 2000, and spawned a sequel,Charlie's Angels: Full Throttle, in 2003.

These films are jam-packed with cameos, but keep your eyes out for an extremely buff Justin Theroux playing a bad guy in the sequel.

10. Christina Aguilera

Clearly Christina Aguilera was a fan of the 'more is more' look in the noughties.

Everything about this look screams noughties - we actually don't think she could have squeezed any more noughties trends into one photo if she tried.

From the heavy-handed self-tan, tiger streaks in her hair, shimmery eyeshadow, corduroy newsboy cap, low-slung baggy jeans - it's all here.

She's even wearing a scarf as a top.

11. Paris Hilton & Kim Kardashian

In the noughties, Kim Kardashian was most famous for being Paris Hilton's friend.

How times have changed...

It seems like Kim learnt from the best though, because she's since eclipsed Paris' fame and then some.

They also used to carry matching metallic Louis Vuitton handbags, because nothing says 'friends forever' like matching designer accessories... Never mind.

12. Jennifer Lopez & Ben Affleck

Easily one of the most iconic pairings of the noughties, we thought Ben Affleck and Jennifer Lopez were going to be together forever.

They even gave birth to the original couple's nickname - "Bennifer" - so how could it not last?

Sadly, these two called off their engagement in 2004, after two years together.

We were surprised, because Ben looked super into it...
