'90s nostalgia just exploded on Twitter.

"Why?" you might ask. Well, super-private couple Sarah Michelle Gellar and Freddie Prinze Jr. shared the sweetest selfie ever taken on Wednesday, March 12, making all of our teenage hearts melt with the burning fire of love.

Now only because this is a special occasion....To all my fans, for your loyalty and support, I thank you. 200,000!!! pic.twitter.com/YwxFl9IDaf

They met on the set of the 1997 teen horror film "I Know What You Did Last Summer," married in Mexico on September 1, 2002, and are parents to daughter Charlotte, 4, and son Rocky, 1.

Nothing gets better than this.
