Kim Kardashian has been doing a bit of reminiscing this week, and posted an eye-popping picture on her Instagram page from her 2011 calendar shoot.
The reality TV star was looking very underdressed in small black knickers, leather thigh-high 'kinky boots', a cool leather jacket and not much else underneath.
She tweeted to her fans: "#tbt calendar glam." We get it, Kim. You were hot.
Back in the present day, KK's still looking fab, and wowed on Jay Leno's last-ever show after 22 years in an all-cream ensemble, featuring a nipped-in peplum waist and stylish pencil skirt.
She uploaded a picture of her with a microphone, writing: "Tune into Jay Leno's last show tonight! Can't wait for u to hear us sing to him 🎶🎤"
Other guests on the show finale included Sheryl Crow and Oprah Winfrey. Kim said: "What an amazing night! Honoured to be a part of The Tonight Show with Jay Leno on his last show with Sheryl Crow, Carol Burnett, Oprah, Jack Black, Chris Paul, Billy Crystal & Jim Parsons. THANK YOU."
And she also kept her followers updated with her show 'look', saying: "Me right now 💜"
Well, we'll give her something: Kim can definitely do sophisticated AND sexy.
