Katy Perry, Demi Lovato, Chloe Grace Moretz, other stars to appear at DNC

Lovato tweeted that she'll be at the convention:

As did Perry:

Actress Lena Dunham, who is also on the star speakers roster, posted an image of her convention-ready manicure.

Moretz also got her nails done in time for the event:

Actress America Ferrera is looking forward to participating and issued a clap-back to anyone who might suggest entertainers don’t belong in the political arena.

“I’m not here as a celebrity, I’m here as a person who has a lot to lose in this election,” she said in an Instagram post. “Please stop telling me to shut up because I’m an actor. I am an American, and like everyone else, there’s a lot at stake for me in this election. I will use my platform and encourage you to use yours.”
