The year was 1999 and teen movies ruled.
From Never Been Kissed and American Pie to 10 Things I Hate About You and Cruel Intentions, some of Hollywood's most up-and-coming stars hit the big screen the year before the millennium and gave us some of the best cult hits of all time.
So, when Cruel Intentions sweetheart Reese Witherspoon shared a #ThrowbackThursday photo of her on the set with co-stars Ryan Phillippe and Sarah Michelle Gellar we were OBSESSED. Obviously.
And because it's already been 15 years (can you believe it?!) since Sebastian Valmont's journal graced theaters, we're bringing you then-and-now photos and details of what the cast has been up to since 1999 — click through the gallery below to see!
Mean girl Kathryn has had a pretty successful acting career since Cruel Intentions — she's starred in the hit films Scooby-Doo and The Grudge as well as on TV shows including Ringer and The Crazy Ones with the late Robin Williams.
Sarah Michelle married fellow '90s teen star Freddie Prinze Jr. in 2002 and the couple have two children, Charlotte and Rocky.
