The Hills ends its run tonight. What memories these cast members have given us!

Heidi Montag's mom on The Hills. This show is mercifully coming to an end very, very soon.

Kristin Cavallari is the star of The Hills, filling in for Lauren Conrad after the show's leading lady bolted. It's not the same, but she tries hard.

The cast of The Hills' final season. It's a bunch we've grown to love, but won't be that sad to see go either.

Brody Jenner, Audrina Patridge and Kristin Cavallari in a promo pic for The Hills. He's hooked up with both of these girls, natch.

Do not mess with the Jenner. Brody is king of The Hills. The guy is a pimp. Recognize.

Kristin Cavallari stares intently on The Hills. She's really good at pretending to be dramatic.
