Yes, somehow, 2008 was 10 years ago.
The iPhone was barely a year old, Instagram didn't exist and Lady Gaga and Katy Perry weren't yet household names.
Here are a few more pop culture moments you won't believe are a decade old this year:
Britney Spears makes a comeback
Britney Spears ended 2008 a lot better than she started it. After a couple years of personal and career struggles that played out publicly, including losing custody of her children and being put on a psychiatric hold, Spears needed a win. She came back strong in the second half of the year with her sixth album, Circus, a guest spot on How I Met Your Mother and three big VMA wins.
The Twilight movie saga begins
It's hard to remember a time without Team Edward and Team Jacob, but back in 2008, the Twilight madness had only just begun. Kristen Stewart and Robert Pattinson starred as star-crossed lovers Bella and Edward in the vampire love story, which sparked a massive following and four more movie installments after its November premiere.
Beyoncé and Jay-Z tie the knot
Before dropping intimate albums and revealing confessions of infidelity, Queen Bey and Jay decided they were crazy enough in love with each other to quietly wed in April of 2008. Not many details about the wedding have been released to the public, but Beyoncé's mom Tina Knowles Lawson shared this adorable snapshot from the nuptials in 2017.
Angelina Jolie and Brad Pitt welcome twins
How times change (RIP Brangelia).
Ten years ago, Jolie and Pitt were still a couple and announced in the spring of 2008 that they were pregnant with the latest additions to their growing brood. They welcomed twins Knox and Vivienne into the world on June 12, 2008.
Sex and the City: The Movie hits theaters
Before the world knew about the ongoing feud between Sarah Jessica Parker and Kim Cattrall, there was Carrie Bradshaw and her girlfriends Samantha Jones, Miranda Hobbes and Charlotte York Goldenblatt in Sex and the City. The successful turn-of-the-millennium TV series, based on the book Candace Bushnell, spawned the movie that hit theaters in May 2008. The film generated a new wave of designer closet lust and raked in more than $57 million its opening weekend.
Miley Cyrus' Vanity Fair shoot causes controversy
Before Miley's twerking days, an April 2008 Vanity Fair shoot was the biggest controversy surrounding the singer. The risqué photo by photographer Annie Leibovitz caused an uproar due to then 15-year-old Cyrus' appearance, which showed her seemingly shirtless, covered only by a large blanket.
High School Musical 3 sings its way onto the silver screen
Zac Efron and Vanessa Hudgens were the stars at the helm of the third movie in the Disney franchise, which made its way from the small screen to theaters nationwide in October 2008. We're secretly hoping for another cast reunion (or another movie) to hold us over.
Heath Ledger's posthumous Dark Knight performance
It's hard to believe 10 years have passed since actor Heath Ledger's untimely death from an accidental drug overdose in January 2008. The 28-year-old's penultimate performance as the Joker in Christopher Nolan's second installment of the Batman trilogy, The Dark Knight, was screened in theaters later that year. The movie received critical and fan praise, particularly for Ledger's maniacal villain. Ledger received a posthumous Golden Globe for best supporting actor.
