The Big Bang Theory taped its series finale earlier this week (we were there) and then, after the taping, there was a wrap party. Because after you wrap 12 seasons of a show, you have a party. The cast was there with their significant others (Hi, Karl Cook!) and they all looked so good. We've said it before, but we'll say it again: no one has aged a day since the show premiered in 2007.

Also walking the red carpet were a bunch of the show's recurring guest stars, including Wil Wheaton, Bob Newhart, Keith Carradine, John Ross Bowie, and Melissa Gilbert, among many others. Take a look in the gallery below.

The Big Bang Theory's one-hour series finale airs Thursday, May 16 at 8/7c on CBS, followed by a special retrospective. The show is available to stream on CBS All Access.
