Cynthia Nixon: Biography, Illness, and Activism

Few television characters have left as lasting an impression as Miranda Hobbes, the sharp-tongued lawyer from Sex and the City. But the woman behind the role, Cynthia Nixon, has lived a life far richer than any script — one that includes a surprise breast cancer diagnosis, a public embrace of her bisexuality, and an audacious run for governor of New York. Here’s what you need to know about the actress, activist, and survivor.

Born: April 9, 1966 (age 58) · Known for: Miranda Hobbes in Sex and the City · Awards: 2 Primetime Emmys, 2 Tony Awards · Spouse: Christine Marinoni (m. 2012) · Children: 3 · Political run: 2018 New York gubernatorial Democratic primary

Eight key facts, one pattern: Nixon’s life is a story of reinvention — from child actor to primetime star, from cancer survivor to political candidate.

Here’s how her public record lines up:

The pattern: Nixon’s career spans five decades and multiple disciplines — a rarity even among A-list actors.

Is Cynthia Nixon LGBTQ?

What does Cynthia Nixon identify as?

• Cynthia Nixon publicly identifies as bisexual. She has stated, “I’m a bisexual woman who has been in a relationship with a man and now a woman” (Wikipedia (open encyclopedia)).
• In later biographical summaries, she has also been described as queer (WordPatch (entertainment biography)).

• Nixon has been an outspoken advocate for LGBTQ+ rights, including same-sex marriage (Wikipedia).
• She received the Vito Russo Award at the GLAAD Media Awards in 2010 and the Human Rights Campaign Visibility Award in 2018 (Fox News (news outlet)).

The implication: Nixon’s sexual orientation is a matter of public record, and she has used her visibility to push for policy change, notably during New York’s 2011 same-sex marriage campaign (The Atlanta Journal-Constitution (regional newspaper)).

What was Cynthia Nixon’s illness?

Cynthia Nixon breast cancer diagnosis

• In October 2006, during a routine mammogram, Nixon was diagnosed with breast cancer (Wikipedia).
• She was 40 at the time and credits the routine screening with catching the cancer early (Cure Today (cancer-focused publication)).

Treatment and recovery

• Nixon underwent a lumpectomy and radiation; she did not need chemotherapy (The Atlanta Journal-Constitution).
• She publicly disclosed her cancer battle in April 2008 on Good Morning America (Wikipedia).
• She has been cancer-free since treatment and became a spokeswoman for the Susan G. Komen for the Cure Foundation (The Atlanta Journal-Constitution).

The pattern: Nixon’s health journey is a narrative of early detection, grace under pressure, and strategic advocacy — a model for public figures facing serious illness.

Who is Cynthia Nixon’s baby daddy?

Cynthia Nixon’s children

• Nixon has three children: Samantha (born 1996), Charles (born 2002), and Max (born 2011) (WordPatch).

Relationship with Danny Mozes

• Danny Mozes is a photographer and was Nixon’s boyfriend for several years in the 1990s and early 2000s (Wikipedia).
• They never married, but remain co-parents to their two children.

The trade-off: Nixon’s family structure — blended, with two fathers across two relationships — is a modern portrait that she has navigated with openness and minimal drama.

Are Sarah Jessica Parker and Cynthia Nixon friends in real life?

On-screen vs off-screen friendship

• Sarah Jessica Parker has called Nixon “family” (Wikipedia).

The catch: The exact nature of the split is private, but the public record suggests a professional distance — not a feud, but a divergence in priorities.
