Kim Kardashian is throwing it back to the Playboy days.
As the Keeping Up With the Kardashians star continues to lay low while caring for her "really happy baby," Saint West's mom is looking back at one of her most memorable magazine covers.
In an Instagram post Tuesday afternoon, the 35-year-old shared a throwback photo from when she was posing for the December 2007 cover. And yes, the cleavage is on full display.
"I found these old photos from my December 2007 Playboy Magazine shoot by Hype Williams and had to post them! They are so good," she wrote on her website. "Awww, I look like a baby LOL! This was probably the first time I met hairstylist Clyde Haygood and worked with him, and also stylist Charlene Roxborough, who I still work with! My makeup was done by Matthew VanLeeuwen."
In the behind-the-scenes pics, Kim models her little red dress that features a plunging neckline that lands below the belly-button. She completes her look with plenty of bling and matching red heels.
Just a few minutes later, the E! reality star showed off another look where she had voluminous hair and a white bikini.
The throwback photos come just one day after Kanye West's wife spoke out about her weight both before and after giving birth to her second child.
In a recent live-stream, Kim admitted that she was 130 pounds when she got pregnant and gained 60 pounds by the end of the journey. As of Tuesday, she had already lost 17 pounds and her goal is to reach her ideal weight of 120 pounds.
"You are looking much better," Caitlyn Jenner told Kim who responded, "I am feeling much better."
Before signing up for any more revealing photoshoots, however, North West's mom remains focused on caring for her two kids.
"It's been some sleepless nights for the two of them still," a source revealed to E! News. "Kim and Kanye are tired, but are enjoying every moment they can…Kanye loves that there is a baby boy in the family now. Kanye is already thinking of melodies for baby Saint."
New episodes of Keeping Up With the Kardashians air Sunday nights at 9 p.m. only on E!
