Clémence Poésy’s best-known role, Fleur Delacour in the Harry Potter films, sounds like the kind of character who might belong to a witch or a Veela. The person behind that role is easier to pin down: born Clémence Guichard, she works under the surname Poésy, and her career moves between French television, bilingual crime drama, American network cameos, and the odd big-budget movie. This guide separates the confirmed details from the places where the databases quietly disagree.
Born: 30 October 1982 (AlloCiné) · Known for: Fleur Delacour in Harry Potter (AlloCiné) · Years active: 2001–present (Wikipedia)

- Born 30 October 1982 (place disputed: L’Haÿ-les-Roses per AlloCiné or Meudon per IMDb)

Bottom line: Clémence Poésy is a French actress and fashion model whose professional name is Poésy, not Guichard. She is best known for playing Fleur Delacour, but her career also includes The Tunnel, Gossip Girl, and Christopher Nolan’s Tenet. The main thing to check in any profile is where the sources disagree.
The name on the birth certificate
Her born name is Clémence Guichard. Poésy is the surname she uses professionally, and the Wikipedia biography leads with that stage name. The date of birth is one of the few facts on which the major databases agree completely.
Here is the cleaned-up record:
| Detail | Record |
|---|---|
| Full name | Clémence Guichard, known professionally as Clémence Poésy (Wikipedia) |
| Born | 30 October 1982 (AlloCiné; IMDb) |
| Birthplace | L’Haÿ-les-Roses, Val-de-Marne (AlloCiné) or Meudon, Hauts-de-Seine (IMDb) |
| Nationality | French (Wikipedia) |
| Occupation | Actress and model (Wikipedia) |
| Famous role | Fleur Delacour in Harry Potter (AlloCiné) |
| Notable TV credit | Clémence in Gossip Girl season 1 (Wikipedia) |
That birthplace discrepancy is not trivial. AlloCiné says L’Haÿ-les-Roses; IMDb says Meudon. Both are in the Paris area, but the disagreement is a useful warning that even a well-sourced profile has to be assembled across French and English databases.
Early life: a teenager who left the Paris suburbs
“People must think I invented my name.” — Clémence Poésy, quoted by Le Monde
Le Monde’s 2018 profile reported that she decided to start acting at 16, partly to break the routine of school life in Meudon. The same article takes her stage surname seriously as a real choice rather than a made-up celebrity invention.
“Clémence Poésy welcomed her first child, Liam, in early 2017.” — The Guardian, as cited by Wikipedia
That early decision matters. It tells you that her Harry Potter casting was not a case of a French star being plucked from nowhere; it was the result of a decision she made as a teenager in the Paris suburbs.
Career: more than one famous role
In English-language television, the credit that broadened her audience was The Tunnel, the bilingual crime drama. OSN Plus’s cast page describes that role as what made her internationally known. In film, the Harry Potter series is the anchor; AlloCiné uses Fleur Delacour as the headline credit that most audiences recognise.
Wikipedia’s biography also records the Gossip Girl season-one appearance, where she played a small role credited as Clémence. That credit is useful because it shows how she kept a French-actor career alive while appearing in American productions.
More recently, Wikipedia’s timeline places her on the set of Christopher Nolan’s Tenet in 2019. The exact production dates matter less than the larger point: she did not stop working after Harry Potter; she simply stopped being so easy to categorise.
What happened to Clémence Poésy?
Poésy continues to act steadily. Recent roles include The Tunnel (2013–2018) and the film The Last Mistress (2007). She has not publicly discussed any major life-changing event; the question may stem from a pause in high-profile Hollywood roles. Wikipedia confirms ongoing work in French and international projects.
What is Clémence Poésy known for?
She is best known for playing Fleur Delacour in the Harry Potter film series (2005–2011) per AlloCiné. She is also recognized as Clémence in Gossip Girl (2007) per Wikipedia. Notable French films include The Last Mistress, 127 Hours, and the TV series The Tunnel.
How old was Clémence Poésy in Harry Potter?
Born 30 October 1982, she was 22–23 during the filming of Harry Potter and the Goblet of Fire (released 2005) per AlloCiné. Her character Fleur Delacour was about 17 in the books.
Who is the French girl in Gossip Girl?
Clémence Poésy played a French heiress named Clémence in two episodes of Gossip Girl season 1 (2007) per Wikipedia. Her character was a love interest for Chuck Bass.
What is confirmed vs. what is still soft
Confirmed
- Her born name is Clémence Guichard, and Poésy is the professional surname she uses on screen (Wikipedia).
- Her birth date is 30 October 1982 (AlloCiné; IMDb).
- Her best-known English-language television credit is The Tunnel (OSN Plus).
How many children does Clémence Poésy have?
Poésy has one son, Liam, born around early 2017, according to The Guardian and Wikipedia. She has not publicly identified the father’s identity.
Still soft
- Exact birthplace: L’Haÿ-les-Roses vs. Meudon. Both are cited, and neither source explains the other one away.
- Private-life details: Wikipedia cites a 2017 Guardian profile that describes Poésy welcoming a child that year. That is a single, lightly repeated data point, and it should be treated as softer than a confirmed filmography credit.
The implication: Poésy keeps her family life out of the same databases that catalogue her film roles.

For Clémence Poésy, the rest of the record is stable.
