Too good not to share! Kim Kardashian may have kept quiet on social media for most of the day, but the reality star saved the best for last when she posted a hilarious throwback picture at the end of the night. On Thursday, Jan. 9, the 33-year-old shared a selfie of herself with Nicole Richie when the women were just 13 years old.

"#ThrowbackThursday @nicolerichie and I being oh so cool at 13 years old," Kardashian wrote. In the photo, the mom of 6-month-old daughter North West and Richie, 32, gave a thumbs up to the camera. The two stars donned white t-shirts, a necklace each, and sported short hair, while Richie wore braces. 

So, how did Richie respond? "Brace Yourselves!" the mom of daughter Harlow, 5, and son Sparrow, 4, joked, as she retweeted the snapshot.

Kardashian is getting a lot of use out of her old, stashed away photographs. On Jan. 6, Kanye West's fiance also posted a throwback picture of herself and the rapper when they attended the Europe MTV Awards in 2012. "#MCM," she simply wrote of her "man crush."
