Once upon a time Back in 2004, Kristin Cavallari and Stephen Colletti were the golden couple of "Laguna Beach" (minus that unforgettable spring break spat). And because today is Throwback Thursday, the mother of three just shared a major blast from the past focusing on the duo's televised dating days.

"Flipping through #BalancingInHeels is a little trip down memory lane," Kristin captioned the priceless smiley pic, above, with her then-beau "Stephennn." "We were babies! Link in bio #LagunaBeach #HighSchool #TBT," she added about the old-school gem. THOSE GRINS AND PEARLY WHITES.

But in all seriousness, doesn't this image of the clearly smitten lovebirds just make you want to say "dunzo" to your day and binge the iconic MTV series this very minute? Or listen to "Come Clean" on repeat? Because, yes, of course it does.

Share your favorite K-Cav and Stephen memories in the comments -- and for another retro rewind, check out a clip of the erstwhile pair during the very first episode of "LB" at the Black and White party below.
