We thought that Kim Richards and Kyle Richards had the longest relationship between Bravolebs on lock considering they've known each other since, well, birth. But Kyle really threw us for a loop when she shared the ultimate flashback picture on Instagram: a picture of her and Bethenny Frankel (see above).

Turns out, the two have known each other long before their Housewives days: according to E! News, Bethenny used to be Kyle's sister Kathy Hilton's assistant—and a babysitter to Paris Hilton!

Kyle's been giving up big revelations about her past recently. Last week, she shared on an episode of RHOBH that she used to have a starring role as Nurse Dori on the hit series ER.

What do you think of Kyle and Bethenny's blast from the past? Let us know in the comments.
