What a send off! Chelsea Handler enlisted her A-list buddies for the most amazing star-studded sing-along finale of her hit E! show Chelsea Lately on Tuesday, Aug. 26.

In a list that reads like a Who's Who of Hollywood, Music and Sport, Jennifer Aniston and Justin Theroux were joined by a host of celebs including Courteney Cox, Gwen Stefani, Vanessa Hudgens, Selena Gomez, Kate Beckinsale, Gerard Butler, Sandra Bullock, LeAnn Rimes, Wiz Khalifa, Tyga and Russell Westbrook to say farewell to the popular talk show host, who has been entertaining fans for seven years.

The jaw-dropping finale saw the celebrity choir sing a takeoff of Michael Jackson’s "We Are The World," and the famous chorus was replaced with the words “Goodbye to E! It’s time to move on. She wants to sing. She wants to dance and get her groove on.”

But it was the celebrity soloists who got the most laughs and screams with their completely hilarious lyrics.

"She can't go on faking every day that Chelsea cares about Kim and Kanye," sang Avril Lavigne.

"She's done with Teen Moms and Justin Bieber, too," added Tim Gunn.

"She's off to Spain to find random guys to screw!" Gerard Butler added, melodiously.
