The two Laguna Beach beauties famously dated the same guy, Stephen Colletti, on the hit MTV reality show that spawned The Hills, which starred Conrad.
In a hilariously contrived move, Cavallari replaced LC as the protagonist and "narrator" of the series in 2009, when she decided to leave after five seasons.
Following The Hills series finale this week, the two reunited along with the whole cast, past and present, at the live after-show bash at the Roosevelt Hotel.
Despite what some think, the two don't hate each other at all.

"We are not going to lunch together and I don’t have her phone number, but we are cool," adds Cavallari of Conrad, who's kept a low profile this past year.
Both girls also dated Brody Jenner at some point.
Speaking of that guy, whose fake relationship with Kristin was a primary, bogus story line this season, he's now with Avril Lavigne - but still close to Kristin.
"Our friendship is the most important thing and I don't think that anything will ever get in the way of that," says Cavallari, who's dating Miguel Medina. (thehollywoodgossip)
