'Chelsea Lately' finale is a star-studded event with shower scenes, singalongs and more debauchery

The last-ever episode of 'Chelsea Lately' was a star-studded live finale.

Not only did the likes of Sandra Bullock, Jennifer Aniston and Mary McCormack show up to stage an "intervention" for the comedian, but there was also a massive celebrity singalong with just about every star you can think of, including Fergie, LeAnn Rimes, Avril Lavigne, Gwen and more.

Special pre-taped cameos included Ellen Degeneres showing up in Chelsea's shower, which, if you recall, is not the first shower fight the show has seen. The popular skit once had Chelsea in a shower slapfest with Conan back in 2013.

And viewers were loving it -- they had '#ChelseaLately' and '#ChelseaLatelyFinale' trending on Twitter throughout.

As for what's next, the comedian is moving to Netflix and will have some comedy specials coming soon. The first is scheduled for October 10th and it can't come soon enough.

Just a few reasons why we're going to miss the booze-loving comedian-author turned late-night host:

She tells it like it is.

She's brutally honest.

It's always written all over her face.

She asks the questions that everyone is thinking.

She's real.

Cheers to Handler.

But of course, Chelsea's show wouldn't be the same without Chelsea's long-time friend, who she warmly refers to as her 'little nugget,' Chuy. You'll be missed. Check out the photos from the singalong below .
