Tamsin Egerton: Relationship with Josh Hartnett, Movies & Family

There’s something quietly refreshing about a British actress who built a solid film career yet chose to live far from Hollywood’s glare. Tamsin Egerton, best known for her role in St Trinian’s, has balanced screen work with a deliberately private family life alongside actor Josh Hartnett.

Born: 26 September 1988 ·
Profession: Actress ·
Partner: Josh Hartnett (since 2013) ·
Children: 4 ·
Height: 5 ft 11 in (1.80 m) ·
Notable films: St Trinian’s, Keeping Mum, The Look of Love

Eight facts that define the actress at a glance:

Are Tamsin Egerton and Taron Egerton related?

• Tamsin Egerton and Taron Egerton are not related despite sharing the same surname. Taron Egerton is a Welsh actor; Tamsin Egerton is British with no known familial connection (Wikipedia).

The implication: The surname coincidence has fooled many fans, but the two actors come from different families and regions – Tamsin from Hampshire, Taron from Aberystwyth.

How did Tamsin Egerton meet Josh Hartnett?

On-set meeting during the film ‘The Lovers’ (2013)

• They met in 2013 while filming the romantic comedy The Lovers (People).
• They began dating after the film wrapped and have been together ever since (E! News).

The catch: Hartnett was a Hollywood heartthrob at the time, but the couple chose to keep their relationship out of the tabloids – a pattern they’ve maintained for over a decade.

How old are Tamsin Egerton’s children?

First child born in late 2015

• Their first child, a daughter, was born in late 2015 in London (People).

Second child born in 2017

• They welcomed a second child in 2017 (People).

Third and fourth children

• A third child arrived in 2019, and a fourth in 2024 (People; E! News).

The trade-off: The family has never disclosed any child’s name or exact birthday, a deliberate privacy choice that makes it impossible to pinpoint their ages with certainty – but the timeline confirms the children range from toddler to school age.

Where do Josh Hartnett and Tamsin Egerton live?

Surrey-Sussex border residence

• The couple lives in southeast England, on the Surrey-Sussex border (Wikipedia).

Privacy from media

• Hartnett has said the children are unaware of who their parents are, reflecting the family’s strict privacy approach (People).

Why this matters: By living in the English countryside rather than Los Angeles, they have largely avoided paparazzi and allowed their children a normal upbringing outside the celebrity ecosystem.

How did Tamsin Egerton get famous?

Early acting start at age 7

• She began acting at around age 6 or 7 in a Royal Shakespeare Company production of The Secret Garden (The Independent).

Breakout role in ‘Keeping Mum’

• Her first major film role was in Keeping Mum (2005) alongside Maggie Smith (The Independent).

Recognition from ‘St Trinian’s’

• She gained wider fame for playing Chelsea Parker in St Trinian’s (2007) and its sequel (Apple TV).

The pattern: Egerton never chased A-list stardom. She left school at 16 with nine A-grade GCSEs to pursue acting (The Independent) and steadily built a career with UK film and TV roles – including Guinevere in the 2011 series Camelot – before stepping back to raise her family.

For fans of Tamsin Egerton, the takeaway is clear: she built a credible acting resume and then chose family over fame. That decision means her future appearances on screen will be rare, but when they come, they will carry the weight of someone who never needed the spotlight to begin with.
