So of course celebs took to Twitter and Instagram to share their latest flashback photos, posting old-school pics for our pre-Friday viewing pleasure.
Kim Kardashian, who we can always count on for a solid Throwback Thursday shot, uploaded a photo with her older sister Kourtney Kardashian this morning, captioning the cute pic, "#TBT @kourtneykardash and I chillin 1998."
The sisters look almost identical as they sit side-by-side, both wearing white tank tops (and a cowboy hat for Kourt!) while sitting in large lawn chairs outside.
But Kim wasn't the only member of the Kardashian clan who took part in Throwback Thursday today. Her sister Khloé also posted an adorable photo from back in the day which featured her late father Robert Kardashian.
"My dad was Batman! Where are my shorts though?!? LOL #tbt," the 29-year-old beauty captioned the sweet shot with her kiddie soccer team.
Can you believe how much the 18-year-old model has grown up before our eyes?!
