It's Thursday again, so let's take a look at all the fun celebrity throwbacks!
First off, expectant mom Megan Hilty got in on the action, posting a comical photo of herself on Twitter holding two glasses of champagne. "#Tbt the year I tried to be a brunette... And a booze hound... Only one of those things stuck," she wrote.
We can easily figure out which one stuck, although the blonde is temporarily on a break for the next six months.
"Anybody can cut hair off, but a barber knows when and where to stop. @MrBarberJ #shoutout #tbt #brooklyn style enhancing my smile," the beauty shared on Instagram.
"#TBT This my stylish little 2nd or 3rd grade self at the zoo presenting my flamingo research paper! (I got an A. Lol) I did the design on my plastic, hot pink visor myself! This is also the beginning of my ten years of orthodontics. HA!," she captioned the shot.
Supermodel Karlie Kloss shared a snapshot in honor of National Siblings Day. In the adorable pic, the Victoria's Secret Angel and her three look-alike sisters lie on top of each on the beach. "This extra special #TBT is dedicated to my 3 incredible sisters. I ❤️ you @kmkloss @kariannkloss @kimbykloss happy #nationalsiblingday!," she wrote.
Meanwhile, Veep star Julia Louis-Dreyfus posted a hilarious naked baby photo of herself on Twitter, poking fun at the mistake on her Rolling Stones cover. The caption read, "#TBT John Hancock not part of tattoo.It is a birthmark.1962 photo is proof. Apologies 2 @RollingStone #crackexcuse."
Finally, House of Cards actress Kate Mara posted a behind-the-scenes pic from the first season of the hit show with co-star Reg E. Cathey. "#TBT Behind the scenes of #HouseOfCards season 1. Freddy trying to read Zoe's emails...," she wrote.
