Reese Witherspoon Shares 'Legally Blonde' #TBT That'll Warm Your '90s Heart— PHOTO

As perennial classic Legally Blonde heads into its 15th year of existence (can you believe 2001 was so long ago?!), Reese Witherspoon and Selma Blair posted an epic throwback on Friday of their time in the film (and the pic came with a hilarious photobomb from Oz Perkins, AKA the chronically-suspicious-looking Harvard Law student who "spent the past year deworming orphans in Somalia"). “Love this and you, @therealselmablair!!” Witherspoon wrote in her version, adding in the decidedly Elle Woods-esque caption, “Think Pink #Regram #FBF #LegallyBlonde."

It's great to see the duo reunited, and the photo makes my Legally Blonde nostalgia stronger than ever — especially when it's cause for hope that another movie is on the way. In an appearance on Fashionably Late with Rachel Zoe last year, Witherspoon teased the idea of a third Legally Blonde , telling the stylist, “I think we’re ready to see Elle and see what she’s up to lately. [...] A lot of writers over the years have come up with different ideas for it. I actually think it’s kind of great right now because we’re talking about women in politics and how important that is to get more women. And I think it’d be kind of a cool thing to have her be a Supreme Court justice or someone who runs for office... [or] President?” Unfortunately, when pressed for details, Witherspoon was quick to add, “Call MGM, I have no idea!”

So sadly, fans might not be getting another sequel anytime soon, but at least we have that reunion photo, right? And Witherspoon and Blair's #TBT isn't the only great on-set photo to thrill fans — here are 11 of the best behind-the-scenes posts from movies and TV.
