"That's what I'm talking about!!!" the former Spice Girl posted to Instagram on Friday, along with a photo of Moretz delivering her speech. "Girl Power!!!! @chloegmoretz @hillaryclinton #ImWithHer us X VB."
Speaking at the DNC wasn't the only way Moretz has spoken out recently. The 5th Wave star wasn't afraid to get involved in the Kim Kardashian/Taylor Swift feud earlier this month -- having it out with Kim's sister Khloe on Twitter.
