Celebrities expected at Democratic National Convention

The 2016 Democratic National Convention kicks off in Philadelphia on Monday, and it's shaping up to be quite the star-studded event.

Slated celebrity speakers run the gamut from 19-year-old actress Chloe Grace Moretz to NBA legend Kareem Abdul-Jabbar.

Moretz wrote on Instagram, "I am so happy to announce I will be speaking At the democratic national convention ! #DNC #ImWithHer going to be such a beautiful historic day and I can't believe I have the immense honor of being part of it. Thank you @hillaryclinton !"

Abdul-Jabbar isn't the only former NBA player set to talk, ABC News reports. Twins Jason and Jarron Collins will also speak for presumptive democratic nominee Hillary Clinton.

Lena Dunham, America Ferrera, Debra Messing and Star Jones will also explain why they're saying, "I'm with her."

There will be other high-profile appearances, including Alicia Keys, Demi Lovato, Eva Longoria and Katy Perry.
