With all due respect to Blake Lively , Reese Witherspoon really is the queen of excellent throwback Instagrams . And no, it's not just because she indulges our undying love for Cruel Intentions . It's because she also indulges our undying love for Legally Blonde.As it happens, Selma Blair (that's the woman playing Kris Kardashian, kids) also starred in both films. Blair shared a snap from the set of Legally Blonde, prompting Witherspoon to gleefully regram it and for everyone else to unleash an Elle-style squeal and reminisce about the good ol' days of late-'90s/early '00s cinema. Those were the days.Here's the photo that has CI/LB fans in rapture.
