Miley Cyrus, Wiz Khalifa, Sammy Hagar, and more joined hands and voices last night during Chelsea Handler's final episode of Chelsea Lately for the "We Are The World" parody "Goodbye to E!"
"She is done with teen moms, and Justin Bieber too," Project Runway host Tim Gunn sang off-key as Alanis Morisette, Avril Lavigne, and Selena Gomez (fresh from her Dave & Buster's date with Justin Bieber) watched with smiles on their faces. New dad Dave Grohl even worked in a joke about the talk show host's longtime sidekick Chuy. Yes, it was a complete and utter mess, but we doubt Chelsea would've had it any other way. Watch the celebrity-packed video above and try to name them all. It's harder than it seems.
