Quick question: what were you doing last night? Were you on 'Chelsea Lately' to celebrate Chelsea Handler's final show? No? Are you sure? Because everyone was there. 

There was Tim Gunn, Gwen Stefani, Sandra Bullock, Gerard Butler, Jennifer Aniston, Justin Theroux, Melissa McCarthy, 50 Cent, Kate Beckinsale, Vanessa Hudgens, Selena Gomez, T.J. Miller, Nev Schulman, Dave Grohl, Joel McHale and Tim Allen, and that is literally just a fraction of the talent that crammed on stage to send her off. Frankly, we were concerned that the whole thing might collapse.

Earlier in the evening, Handler completed one final interview -- with Ellen DeGeneres ... in a shower ... while Handler was naked. Hey, some things never change. Chelsea Handler is one of them.

And here is Handler's heartfelt final goodbye. It's okay to get misty.
