Update: Watch This Space

Update: Looks like we're going to have to eat our cloche. Kristin Cavallari did show up to Lauren's fashion show last night, as well as Stephen Colletti and Brody Jenner. Reunited and it feels so good.

A reconciliation is in the works between Lauren Conrad and Kristin Cavallari.

L.C. invited her former Laguna Beach nemesis—they feuded over where-is-he-now costar Stephen Colletti—to her runway show today at Smashbox Studios, part of L.A.'s Mercedes-Benz Fashion Week. 

And Kristin accepted.

"Yeah, we've been cool with each other for a long time," Cavallari tells E! News.

But that doesn't mean Cavallari's gonna appear on The Hills. "Kristin has said she doesn’t need to do The Hills or any reality TV anymore," a source tells Life & Style.

And frankly, we'd be surprised if she actually shows tonight.

The countdown to togetherness (or not) begins...
