Kardashian, 35, is pictured wearing a skintight black dress as she posed as Posh Spice (of course ... don't really see Kim Kardashian dressed as Sporty Spice) writing, "I'm so Thankful that me & my friends were the Spice Girls for our high school talent show! The Spice Girls got me through a lot! #ForeverThankful"
Kim is nearing the end of her pregnancy and she and husband Kanye West, who are awaiting the arrival of a baby boy to join sister North West, were resting up on Wednesday, spending some time looking through old photos, according to Us Weekly.
She shared another throwback pic of herself at 18 with sister Khloe Kardashian.
"When you're sick in bed & going through old pics! Khloe don't kill me lol This was my 18th birthday & Khloe took me to a Backstreet Boys concert! #WhatAreThoooseHats"
On Thursday, Kim Kardashian took even more time to express the 10 things she is most grateful this Thanksgiving on her website.
"Thanksgiving is a day for spending time with my whole family, eating delicious food and being thankful for all the amazing blessings in our lives. Here's what I'm thankful for this year," she wrote in a post that showed her with her husband and daughter, North West.
"1. The love of the greatest mom in the world; 2. A loving husband; 3. A happy daughter; 4. A baby boy on the way; 5. The opportunity to work on projects I love; 6. Sisters who will be there for me no matter what; 7. My health — I never take that for granted; 8. Lifelong friends from all over the world; 9. My fans — they're so passionate and loyal; 10. Nieces and nephews who always make me laugh and are the best friends to North."
