The pregnant E! star posted an old pic of the parents-to-be dressed up in retro-inspired outfits earlier today in honor of Throwback Thursday.
"#ThrowbackThursday #GatsbySwag," Kardashian tweeted along with a shot of them.
In the pic, Kim sports a white fur, jeweled necklace and earrings, red lips and a flapper-inspired curly bob hairdo. Kanye looks dressed to the nines in a white tuxedo and black bowtie.
Britney Spears also got in on the Throwback Thursday fun today. The singer shared a pic of herself from the "Oops!... I Did it Again" music video with the caption, "#TBT can't believe it's been 13 years since the Oops album came out... Holy moly!"
