Trachtenberg, a New York City native, made her acting debut as a child star with roles in Nickelodeon projects, including the television series “The Adventure of Pete & Pete” and the film “Harriet the Spy.”

Her big break came when she was cast on “Buffy the Vampire Slayer” as Dawn, the younger sister of Sarah Michelle Gellar’s titular character, from 2000 to 2003. The role earned her a Teen Choice Award nomination for choice TV sidekick in 2001.

Trachtenberg recently reminisced on her days co-starring with Gellar on “Buffy.” Just last month, she shared a photo of them together, captioning it: “Slay all day! Always loved this twinning photo of us! #buffy #dawn #sister #womancrushwednesday.”

The actress also made a cameo in Fall Out Boy’s music video for the band’s hit song “This Ain’t a Scene, It’s an Arms Race” in 2007.

Trachtenberg starred as Georgina Sparks on “Gossip Girl” from 2008 to 2012. For her role, she was nominated as the choice TV villain at the Teen Choice Award in 2012.

“It’s kind of easy to be evil when you’re saying evil things,” said Trachtenberg of her “Gossip Girl” role to Seventeen in 2009. “It’s definitely a lot more fun than playing the good girl. I love the reaction you get. I never understood why some actors don’t want to play villains or evil characters.”

Trachtenberg has also appeared in a wide range of television shows, including “Mercy,” “Weeds,” and earlier in her career, ‘Truth or Scare.” She had a minor arc in HBO’s “Gossip Girl” reboot in 2022.

In film, she took on roles including “EuroTrip,” “17 Again” and “The Scribbler.”
