A certain Mean Girls meme probably flooded your feeds this weekend to mark a monumental day: October 3rd. Yes - the day that Cady Heron told certified hottie Aaron Samuels in math class what day it was.
Since the film became the teen flick to end all teen flicks, 3 October has gone down in history as Mean Girls day, and the cast made all of our greatest hopes come true by reuniting.
Lindsay Lohan (Cady), Daniel Franzese (Damian), Rajiv Surendra (Kevin Gnapoor), 'cool mom' Amy Poehler, Lacey Chabert (Gretchen Wieners) and Lizzy Caplan (Janis Ian) hung out to mark the 11th anniversary of the film, and Daniel was particularly Instagram-happy on the occasion posting this string of photos.
Ok, so there was no Rachel McAdams, or Amanda Seyfried.
But we're proud of the rest of them for making it happen.
See what more of our favourite teen movie and TV stars look like now in the gallery below...
Then and Now TV and Film
Clueless
Alicia Silverstone exploded onto the screen as Cher Horowitz in the now-cult 1995 film, shopping and matchmaking her way across Beverly Hills.
Clueless
While Cher and Josh were the most important romantic pairing of the film, her pal Dionne, along with boyfriend Murray (played by Donald Faison), were the relationship that taught audiences most about the ups and downs of teenage romance.
Clueless
Since Clueless was released, Dash has posed naked for Playboy, starred in Kanye West's music video for 'All Falls Down', and changed her political affiliation from Democrat to Republican.
Clueless
Following hit comedic roles in Friends and Forgetting Sarah Marshall, Paul is Marvel's newest superhero Ant-Man, in cinemas July 17th.
The Hills
From the dreamy opening shot of LA, to the endless stream of hot guys, The Hills presented a life we all knew was fake but wanted to live anyway. It paved the way for our current obsession with Keeping Up With The Kardashians, and introduced the world to Speidi.
The Hills
A member of America's favourite extended family, Brody Jenner has dated everyone from childhood friend Nicole Ritchie to Avril Lavigne - or so we think. He recently admitted of The Hills, 'A lot of that show was scripted. Lauren's a dear friend of mine. We were just friends.' He now has a four-part chat show, 'Sex With Brody'.
The Hills
Definitely the brains of the show, Lauren Conrad now runs a lifestyle blog professing to give us 'a front-row pass to all things lovely and chic', where she holds a book club on our favourite chick lit and reveals her style and beauty secrets to her fans.
The Hills
Since The Hills ended in 2010, Kristen Cavallari has turned her California girl style into a jewellery and shoe design business, enjoying a career in acting along the way. She is expecting her third child with husband Jay Cutler.
The Hills
Younger sister of Spencer, Stephanie Pratt has graduated from American reality television and found her home in London, or more specifically Chelsea. Stephanie now appears on Channel 4's Made In Chelsea, and is happily dating Josh Shepherd.
The Hills
Audrina Partridge had her own short lived reality show, Audrina, on VH1 after The Hills ended, going on to film scenes for Scary Movie 5 that were removed from the final cut. She currently hosts a late night travel show called 1st Look.
The Simple Life
So close and so alike everyone swore they were sisters, Paris Hilton and Nicole Richie were the queens of reality television way back when the Kardashians were a blink in the E! Channel's eye. Slightly ridiculous but always entertaining, the show launched the pair, as well as Paris' catchphrase 'that's hot', into the stratosphere.
The Simple Life
While Paris perfectly fulfilled the role of the bubbly socialite, we always had high hopes for Nicole, with her wicked sense of humour. Nicole now has two children with Joel Madden and two fashion lines, House of Harlow 1960 and Winter Kate.
The Simple Life
Since her rise to fame, Paris has been criticised by the media for being famous without any talent or handwork, much like ex-best friend Kim Kardashian. But she can currently claim to be a singer, one of the world's highest paid DJ's, and a true pioneer of reality TV.
The O.C.
We fancied Ryan, we wanted to be Marissa, we rooted for Seth and we loved Summer. These four, along with their friends and parents, taught us that life in society's upper echelons wasn't all it's cracked up to be. We laughed and cried alongside them all the way through our teenage years. The show was as close to perfect as a teen series could get, and who could forget the image of Ryan carrying Marissa away from a burning car?
The O.C.
The world was Mischa Barton's oyster, until she began to run into legal troubles in what looked like a case of life imitating art. Nowadays, Mischa seems happy and relaxed, a far cry from Marissa and her troubled years.
The O.C.
Rachel starred in Hart of Dixie until it was cancelled earlier this year, and has a baby girl, Briar Rose, with boyfriend Hayden Christensen.
The O.C.
Adam Brody was stellar as Seth Cohen, expertly playing out his romance with Summer using his geeky charm and witty one-liners. Adam dated co-star Rachel for three years, but ultimately found love with Gossip Girl star Leighton Meester, who he married in 2014 and is currently expecting a baby with.
One Tree Hill
Another amazing high school TV show, One Tree Hill introduced the world to the god that is Chad Michael Murray. The family-oriented plot gave the show an edge on other teen dramas, and it actually made us interested in basketball. Kind of.
One Tree Hill
Hilarie Burton continues her acting career with a role in Extant, as well as being the full-time Mrs Jeffrey Dean Morgan. Bethany Joy Lenz has since had a growing career as a singer and musician, as well as continuing to act.
One Tree Hill
Sophia Bush went on to star in another cult film favourite, John Tucker Must Die. Currently starring in Chicago P.D, Sophia is a dedicated activist and is the co-founder of I Smell Great, a cutting edge perfume company.
One Tree Hill
Hearts around the world broke when Chad Michael Murray married actress Sarah Roemer in early 2015, and shortly after she gave birth to their son. Unfortunately the height of Chad's popularity was in the early-mid 2000s, but as long as Chad is still acting, hearts are still melting.
Cruel Intentions
Bringing 18th Century French fiction to 20th Century teens, Cruel Intentions was dark, sexy and dangerous. Giving many of today's biggest actors their introductions to the big screen, it launched the careers of the likes of Reese Witherspoon and Sarah Michelle Gellar.
Cruel Intentions/Buffy the Vampire Slayer
Sarah Michelle Gellar was in the middle of Buffy fever when she starred in Cruel Intentions, eventually spending six years on everyone's favourite vampire slaying TV series. She's been married to Freddie Prinze, Jr. since 2002.
Cruel Intentions
Reese Witherspoon has had roles as diverse as June Carter Cash and Elle Woods, proving her versatility as an actress. She received her first Oscar in 2005 and her star on the Hollywood Walk of Fame in 2010.
Cruel Intentions
Ryan Phillippe had an 8 year relationship with co-star Reese Witherspoon, during which time he starred in critical successes Gosford Park and Crash. He has two children with Witherspoon, and one with actress Alexis Knapp.
Buffy the Vampire Slayer
Long before Twilight, Buffy the Vampire Slayer was the trendy supernatural teen show to be seen watching. The show wasn't just a hit with teenagers though, it was a critical success that snapped up its fair share of Emmys.
Buffy the Vampire Slayer
Alyson Hannigan married her Buffy co-star Alexis Denisof in 2003, and is most famous for her role as Lily Aldrin on How I Met Your Mother. Seth Green married actress Clare Grant in 2010, and has had roles in Family Guy and all three Austin Powers films.
Buffy the Vampire Slayer
Charisma Carpenter has continued her roles in supernaturally themed television, appearing in the Buffy spin-off Angel, as well as Charmed.
Clueless
Looking back now, it was slightly weird that he was Cher's ex-stepbrother, but at the time Josh Lucas, played by Paul Rudd, was every 90's girl's dream crush.
Clueless
Alicia Silverstone is now an author and natural living guru. Her book The Kind Diet promotes her strict vegan lifestyle. She has also written about being a mother, called The Kind Mama - but its advice, which included telling parents to avoid vaccinations, caused controversy when it was published.
The Hills
On The Hills, he was a moody, tattooed heartbreaker with a motorbike, surly tone and amazing hair, and dated Audrina Partridge.
The Hills
Now, Justin Bobbi Brescia is in two-man band Bobby Rock, but he's mainly a hairdresser, with salons in LA and NYC, and a line of products called Brush Your Hair.

Ben McKenzie, who played Ryan, literally hasn't aged since the show aired. Now he plays Commissioner James Gordon in TV show Gotham, a pre-curser to the Batman movies.
Cruel Intentions
Selma Blair (pictured here with her son Arthur Saint) recently starred in TV show Anger Management, alongside Charlie Sheen.
