It's been seven years since Chelsea Handler made her late night debut as the host of E!'s Chelsea Lately, and what a difference seven years makes: The author of four books (and bestie to A-listers like Jennifer Aniston and Reese Witherspoon) is now a household name. And though she has been known to throw punches at E!, the network that airs her show, Chelsea Lately has undeniably been a huge factor in her rise as an entertainment power player.

This all being said, as we've witnessed all kinds of debauchery on the show, it was only fitting that its finale last night was a culmination of such shenanigans—and that it, of course, involved many of Handler's most high-profile guests (and friends). From showering with Ellen DeGeneres to a star-studded sing-along, here's how it all went down:

First, Handler was shown mid-shower (camera crew in tow) when Ellen DeGeneres interrupted to demand to know why she hadn't yet been invited to appear on the show. A heated discussion involving shy nipples and Ryan Seacrest ensued:

Next, Mary McCormack, Jennifer Aniston, and Sandra Bullock took their spots on the show's couch to stage a series of interventions. McCormack claimed that "Netflix" (where Handler is headed next for a stand-up and TV deal) is actually code for rehab, Aniston's grievance was that Handler has copied her in everything from her hairstyle to her eye color, and Bullock cleaned out the host's desk for her, only to be horrified by its contents:

Then it was time to bid adieu to E!—somewhat ironically of course, since regular viewers know that Handler has never hidden her feelings about the network. And what a goodbye it was—in a sing-along to the tune of "We Are the World," the stage was packed with the likes of Gwen Stefani, Fergie, Avril Lavigne, Chloë Grace Mortez, Tim Gunn, Pharrell, Dave Grohl, Gerard Butler, Selena Gomez, Miley Cyrus, LeAnn Rimes, Kate Beckinsale, Alanis Morissette, and oh, basically every other celebrity who ever existed. It was just that much of a reminder of the big-name fans that Handler has in her corner:

And since this is Chelsea Lately, Chelsea herself made her last sign-off—that is, for now:

We've watched the show from the very beginning, so it's bittersweet to see it end. But we can only imagine what the next seven years will bring for Chelsea Handler—beginning with what we're sure will be a binge-worthy Netflix debut.
