5 things to know about convention speaker Chloe Grace Moretz

Hillary Clinton has already been endorsed by a star-studded line-up at the 2016 Democratic National Convention. As the final day of the convention kicks off, one of the slated celeb speakers stands out because she's barely old enough to vote: Chloe Grace Moretz.

The 19-year-old actress announced on Instagram last week that she would be traveling to Philadelphia to speak at the DNC. She has been tweeting her reactions to the convention all week as it unfolded, including when Clinton officially accepted the nomination.

Here are five things to know about the actress before her big speech on Thursday.

What you might recognize her from

The teen has been acting most of her life, appearing on television in 2004 in The Guardian. Her TV credits since then include playing Kiki George on Dirty Sexy Money and Kaylie Hooper on 30 Rock. She's also been on the big screen, including films like Kick-Ass, Hugo and, most recently, Neighbors 2.

Why she's saying, "I'm with her"

Moretz is hardly a new supporter of the presumptive Democratic nominee. She stumped for Clinton at an event in February, when she told People magazine she liked her college loan reform plan.

Moretz said women had told her early on in the campaign they were afraid of being labled "strict feminists" if they supported Clinton. Her response to them was, "Don't be afraid to vote for Hillary just because she's a woman. Vote for Hillary for the things that she stands for."

She has a famous beau

It seems young (celebrity) love is in the air. In May, Moretz confirmed she is dating Brooklyn Beckham, the teenage son of David and Victoria Beckham. Since then, the pair has been social media gold. One recent photo of the young couple racked up more than 750,000 likes on Instagram.

Her Instagram game is strong

Between her Hollywood lifestyle and her high-profile relationship, it's no wonder Moretz has attracted a whopping 9.4 million Instagram followers. That's no small feat, though she has a long way to go before she reaches Instagram queen Selena Gomez's 91 million followers.

She's not afraid to voice her opinion

Moretz most recently made headlines when she weighed in on a rift between Taylor Swift and Kanye West. It involved West's reference to Swift in his song "Famous." In a video Kim Kardashian West released last week, the rapper is in the recording studio and Swift's voice can be heard telling West she respects him for speaking to her about the lyrics before the song came out. The video triggered backlash against Swift, who said that she took issue with a different line than what was being discussed in the video.

While Swift and West's respective supporters were coming to their defense, Moretz tweeted that the music industry was preoccupied by the wrong things.
