Watch: Miley Cyrus, Selena Gomez And Jennifer Aniston Help Sing Goodbye To 'Chelsea Lately'

All the stars.

Chelsea Handler promised to go out with a bang, and true to her word, Tuesday night's grand finale of "Chelsea Lately" was a star-crammed spectacular. The comedian ended her seven-year run with a "We Are The World"-style sing-along that featured a galaxy of her A-list friends, including Miley Cyrus, Vanessa Hudgens, Selena Gomez, Gerard Butler, 50 Cent, Avril Lavigne, Wiz Khalifa, Melissa McCarthy, Gwen Stefani Justin Theroux, Dave Grohl, Tyga, Jennifer Aniston and Anna Faris.

Plus way, more than that, but you'll just have to take our word for it and scan the stage for your favorites in this musical number called "She Wants To Sing." (Also, look for Stefani making fun of herself for her verbal slip-up while presenting at the Emmys on Monday night.)
