US actress Michelle Trachtenberg, known for her roles in Buffy The Vampire Slayer and Gossip Girl, has died aged 39.
The New York police department confirmed her death to the PA news agency in a statement on Wednesday.
The police said they responded to an emergency call at around 8am on Wednesday to One Columbus Place in New York and Trachtenberg was later confirmed dead after emergency medical services attended.
Her death is not being treated as suspicious and the police said the medical examiner will determine her cause of death.
Born on 11 October, 1985, in New York City, Trachtenberg began her acting career at the age of three, appearing in adverts before landing roles on TV.
In 1992 she secured a recurring role in children's sitcom The Adventures Of Pete & Pete and in 1996 she starred in film Harriet The Spy as an 11-year-old given to spying on neighbours and classmates, and concocting outrageous lies to embellish the everyday details in her private journal.
She was also known for playing Penny in 1999 spy film Inspector Gadget and Jenny in 2004 movie EuroTrip.
In 2005 she starred opposite Sex And The City actress Kim Cattrall in Ice Princess and was also in 2009 teen comedy 17 Again alongside Zac Efron.
More recently Trachtenberg reprised her role in the second series of the Gossip Girl sequel.
The actress, who was born in Manhattan and grew up in Brooklyn, told the XOXO podcast with Jessica Szohr she knew a lot of people from the Upper East Side, in her 20s, who were "very similar to the Gossip Girl characters and involved in that world", adding "and some were actually more scandalous than the show portrayed".
Trachtenberg's Buffy The Vampire Slayer co-stars paid tribute to the late actress on social media, with Emma Caulfield saying the cast had "lost a little sister".
