Kristin Cavallari Just Made Us Fall In Love With Stephen Colletti Again

Remember that reality show "Laguna Beach"?

Anyone? Anyone? I'll give you a hint: "The Hills" was its spin-off. Ahh, now you're all with me!

You know who does remember, though? Kristin Cavallari. Kristin is bringing us all down memory lane too by posting this adorable Throwback Thursday pic of her and co-star Stephen Colletti.

The caption reads,

Flipping through #BalancingInHeels is a little trip down memory lane. We were babies!

Awww! So cute!

It looks like the photo's from the first season of "Laguna Beach," in 2004, when Kristin was a high school junior and Stephen was a senior.

Now, Kristen is 29 and Stephen is 30. Stephen quit reality television for good after "Laguna Beach," and later went on to play Chase Adams on "One Tree Hill." But we'll always have a soft for that 18-year-old kid.

'Course, he's not too bad looking these days, either!

Yep, Stephen's all grown up now, he and really knows how to rock a shirt and tie.

Just like you, he's in a very serious relationship with his Netflix account.

Imagine the fights Kristin and Lauren Conrad would have over this version of Stephen, though.

(If both ladies weren't already happily married, that is.)

Looking good, Stephen, both then and now!
