Gillian Anderson: Partner, X-Files Feud, Teetotal & More

From her iconic role as Dana Scully on The X-Files to her recent turns as Margaret Thatcher and Jean Milburn, Gillian Anderson has built a career out of reinvention.

Seven key facts, one pattern: Anderson’s public persona is anchored by a consistent set of biographical details — birth, family, career milestones — while her private life remains deliberately opaque.

Does Gillian Anderson have a partner now?

Who is Gillian Anderson currently dating?

Gillian Anderson is widely reported in 2025 entertainment coverage as being in a relationship with screenwriter and producer Peter Morgan, though reports also note that the pair are highly private (HELLO! (celebrity news outlet)). Multiple 2025 reports say they have not lived together during their relationship. A 2025 article from The Mirror (UK tabloid) states Anderson is not thought to be dating anyone else and that her last long-term relationship was with Morgan.

Has Gillian Anderson ever been married?

Anderson has never been married, but she has been engaged twice. She was engaged to documentarian Julian Ozanne in 2008 (ended 2008) and to Peter Morgan in 2016 (ended 2020). She has three children from previous relationships: daughter Piper Maru (born 1998, with Clyde Klotz) and sons Oscar (born 2006, with Julian Ozanne) and Felix (born 2008, with Mark Griffiths).

The implication: Anderson’s private life remains a carefully guarded domain, and public confirmation is unlikely.

Are Gillian Anderson and Peter Morgan still together?

What is the latest on Gillian Anderson and Peter Morgan’s relationship?

Media coverage says Anderson met Peter Morgan while working on The Crown in 2016 (HELLO!). They were reported to have split around 2020 because of demanding schedules. However, the pair were seated together at the 2024 Emmy Awards, leading to widespread reconciliation rumors (HELLO!). A 2025 article from The Mirror (UK entertainment site) says they first became romantically linked in 2016 and had a four-year relationship before the reported split. Neither has publicly confirmed a reunion.

The pattern: Anderson and Morgan guard their privacy fiercely. Public appearances together are rare, and neither uses social media to confirm or deny the status. For fans, the clearest signal remains whether they are photographed together at industry events.

Why did David Duchovny and Gillian Anderson fall out?

What was David Duchovny accused of?

David Duchovny and Gillian Anderson had a reported falling out during The X-Files due to creative differences. Duchovny was accused of being difficult to work with on set (HELLO!). The two have since reconciled and maintain a friendly relationship. In interviews, both have acknowledged past tensions but now speak warmly of each other.

What this means: The Scully-Mulder chemistry on screen was real, but the actors behind the characters had their own off-screen dynamics. The feud was never a full-blown war — it was a professional relationship with occasional friction that has since smoothed out.

The trade-off: Anderson’s public persona is carefully curated. She is approachable but not overly revealing, friendly but guarded. Fans who meet her often describe her as warm, but she maintains boundaries that keep her private life separate.

With a packed slate of 2025 projects — Trespasses, The Abandons, and Tron: Ares — Anderson shows no signs of slowing down. For audiences, the clear choice is to keep watching Gillian Anderson evolve, or risk missing the next chapter of a career that refuses to be boxed in.
