The Democratic National Convention has tapped Chloë Grace Moretz and Debra Messing, both long-time supporters of presumptive Democratic nominee Hillary Clinton, to speak at its party convention, kicking off July 25 in Philadelphia.

Moretz broke the news on her Instagram, writing, “[It’s] going to be such a beautiful, historic day and I can’t believe I have the immense honor of being part of it.”

Messing had the same sentiment, writing on Twitter, “So honored to be speaking at the Democratic Convention. Truly.”

Both stars shared photos with the former Secretary of State, below.

The full line-up for the DNC has yet to be announced, but President Barack Obama, First Lady Michelle Obama, President Bill Clinton, Vice President Joe Biden, and Senator Bernie Sanders are all set to speak at the four-day convention.
