Here’s a fact-checked look at what’s known about his life and what isn’t.

Five facts form the core of Smith’s biography, one pattern: each marks a turning point in his public life.

Is Matt Smith in a relationship?

Who is Matt Smith going out with?

Smith’s current relationship status has not been publicly confirmed. Media reports consistently link him to actress Lily James between 2014 and 2019, but the actor has not spoken publicly about any new relationship since their split (TV Insider (celebrity biography site)).

Who is Matt Smith married to?

Smith has never been married. No public records or credible reports indicate a marriage at any point in his life.

Does Matt Smith have any children?

As of 2025, Matt Smith has no children. Neither he nor any past partner has announced a pregnancy or child.

The pattern: Smith keeps his private life tightly controlled. What’s publicly known about his romantic past comes almost entirely from journalistic reports, not from his own disclosures.

What medical condition does Matt Smith have?

Has Matt Smith got ADHD?

Matt Smith has ankylosing spondylitis, a chronic inflammatory form of arthritis that primarily affects the spine. He has spoken openly about the condition in interviews, noting it causes pain and a slight limp (Wikipedia (biographical encyclopedia)). There is no confirmed diagnosis of ADHD; online speculation remains unsubstantiated.

The takeaway: Smith’s health condition is a verified part of his life, but the ADHD claim lacks any credible source and remains a fan-theory.

Are David Tennant and Matt Smith friends?

Is Matt Smith nice in real life?

Colleagues and co-stars describe Smith as professional, kind, and eccentric. David Tennant, who played the Tenth Doctor before Smith, has publicly praised his successor and the two remain friends (SYFY (entertainment news site)). Smith’s improvisational style and energy on set have been noted by directors and fellow actors (Gizmodo (entertainment and tech publisher)).

Is Matt Smith pro LGBTQ?

Smith has publicly expressed support for LGBTQ+ rights and inclusion, but he has not issued a formal statement or aligned with a specific campaign. His portrayal of Prince Philip, a figure of rigid tradition, contrasts with his off-screen views.

The implication: Smith’s reputation as a “nice guy” is widely attested by those who work with him, and his friendships cross franchise lines.

How rich is Matt Smith?

Matt Smith’s net worth is not officially disclosed. Third-party trackers estimate it in the range of $8 million, derived primarily from his lead roles in Doctor Who, The Crown, and House of the Dragon (TV Insider (celebrity biography site)). His annual salary for Doctor Who was not made public, but the show’s main actors have historically earned in the six-figure range per season.

The catch: without a confirmed net worth figure, any number is an estimate. The real story is Smith’s career longevity across high-budget productions.

What is Matt Smith’s personality like?

Smith is frequently described as eccentric, energetic, and thoughtful. In interviews, he jumps between topics with a kinetic, almost improvisational style — a trait that carried directly into his portrayal of the Eleventh Doctor. Co-stars on House of the Dragon have noted his professionalism and ability to lighten the mood on set (Gizmodo (entertainment and tech publisher)).

The pattern: Smith’s personality is part of his brand — a high-energy, slightly unpredictable actor who never quite fits the usual star mold.
