Because it's pretty much exactly what she would have wanted.
Among them were Andy Cohen, Whoopi Goldberg, Howard Stern, Hoda Kotb, Diane Sawyer, Ozzy Osbourne and his daughter Kelly Osbourne, Kathy Griffin, Sarah Jessica Parker and her husband Matthew Broderick, Giuliana Rancic, Alan Cumming, Barbara Walters, Hugh Jackman, Dr. Oz, Kathie Lee Gifford, Donald Trump, Joy Behar, Michael Kors, and of course Rosie O'Donnell.
Like we said, they allllllll came out to remember Joan.
During the service, there were various musical performances to pay tribute to Joan.
The funeral began with the New York City Gay Men's Chorus serenading the crowd. Then our favorite Audra McDonald performed Smile originally by Charlie Chaplin, that brought the house down…. and left most people in tears.
Howard Stern also gave a speech that managed to be both hilarious and emotional at the same time.
He said Joan:
'[Joan was] the best friend in the world, a big sister, a crazy aunt at a bar mitzvah. She fought the stereotype that women couldn't be funny. She was responsible for putting the red carpet into prime time.'
Later in the service, Melissa paid tribute to her late mother by reading a letter she'd written to her mom that elicited laughter from the whole crowd.
She ended her speech with many thanks to those in attendance.
'We are humbled. I am grateful for everyday Cooper and I have with you. You are an inspiration.'
Then towards the end of it all, Hugh Jackman serenaded the crowd with a gorgeous version of Quiet Please, There's a Lady on Stage, because that's exactly what Joan deserved.
The last and most wonderful thing of all was that the crowd exited to the sound of New York, New York played on bagpipes by the Pipes & Drums of the Emerald Society.
Oh, and of course there was a red carpet for the guests to walk in on.
The memorial service was almost exactly as Joan would have wanted it. Perfection.
We'll miss you, Joan.
