Kim Kardashian took a sexy walk down memory lane on Tuesday.

Less than two weeks after giving birth to her son, Saint West, the 35-year-old reality star decided to share some images of herself before she was a mother of two. "At this time back in December 2007 I shot my Playboy cover with Hype Williams," she captioned an Instagram pic of herself at age 27, wearing red lingerie.

Kim also shared another pic with her 54.6 million Instagram followers of herself wearing a mod-like white swimsuit for the Playboy spread.

Prior to sharing these sexy flashback photos, Kim revealed during a livestream on her mobile app that she had gotten up to 190 pounds during her most recent pregnancy and was now looking to lose some weight.
