Henri Thynne made his name on social media but he is now known for very different reasons.
In June 2025 the fitness influencer was sentenced to three years in prison after pleading guilty to domestic violence offences.
This is the story of his rise and fall >>>
Family matters
Henri, 21, is the younger half‑brother of influencers Tammy, Amy and Emilee Hembrow.
Most famously Tammy, born 1994, is a well-known Australian fitness influencer, entrepreneur, and former reality TV contestant.
Henri and the Hembrows have the same father – Mark, an actor and musician – while he has other siblings Ava, Starlette and Max.
Social media stardom
Henri followed in his older half-sister Tammy’s footsteps on the road to the fitness industry.
He first gained traction by showcasing his dramatic physical transformation over a couple of years.
He became notably active on Instagram and TikTok, where his efforts paid off.
On Instagram he rose to have more than 100,000 followers, with regular posts featuring workout clips, physique updates, and lifestyle content
On TikTok he has about 192,700 followers and 4.7 million likes.
Steroid allegations
In 2022, he addressed claims of steroid use after dramatically changing his physique in just two years.
When asked on Instagram if he was natural, Henri replied with a meme that read: “That’s a nice argument you have there. Unfortunately my muscles are bigger than yours.”
“Was tired of being a small sad nerd (c***),” he added.
He had previously denied allegations of steroid use.
Henri came to prominence in November 2022 when he shared a number of photos on Instagram and TikTok showing his transformation.
“Not gonna stop till I’m number 1,” he wrote in one post.
When sentenced for DV offences in 2025, Judge Brad Farr said Henri’s steroid use was no excuse for his behaviour.
The court heard he had been in custody for almost a year and stopped steroids, dropping 20kg.
“Your behaviour was extraordinary,” Judge Farr said.
“It is to be hoped you have the maturity and intelligence to overcome that steroid use … and not be a menace to society as you have in recent times.”
Missed wedding
Henri was notably absent from Tammy Hembrow’s recent wedding to Matt Zukowski due to his incarceration at the Arthur Gorrie Correctional Centre.
Henri was facing charges related to domestic violence offences, of which he was ultimately convicted.
Despite his absence, Tammy’s wedding at Chateau Du Soleil in Byron Bay was a fairytale event attended by her father, sisters, and other half-siblings, who celebrated in style.
The ceremony featured Tammy’s sisters and half-sisters as bridesmaids, while her children took on special roles, adding to the day’s joyous atmosphere.
Tammy’s daughters Saskia, 8, and Posy, 2, were flowergirls, while her son Wolf, 9, served as a page boy.
Tammy’s other half-brother Max, 16, also attended the wedding.
Claims of sister support
There was controversy before Henri’s DV sentencing when Tammy Hembrow denied claims she supported her jailed half-brother.
Outspoken influencer Mikaela Testa, an anti-sexual assault campaigner, posted a TikTok outing Hembrow for backing her brother.
But in a video Hembrow insisted she had “no involvement whatsoever” in Henri’s case.
“I haven’t bailed him out. I don’t condone violence. I haven’t spoken to him,” she said.
DV conviction
Henri’s domestic violence victim bravely stared down her “menace to society” abuser as she detailed how the terrifying ordeal shattered her life.
Henri pleaded guilty to a number of domestic violence offences including common assault, stalking and two counts of strangulation in June 2025.
Brisbane District Court heard during one incident the couple were watching a movie when Henri elbowed her in the head and called her a “c***” after she tried to cuddle him.
The court heard she was so fearful that she packed up and moved interstate.
In a powerful victim impact statement the woman said no words could capture what she had been through.
His barrister Greg McGuire, instructed by Jahnke Lawyers, said the couple had an “odd” relationship with both of them being bodybuilders and having a social media presence.
Judge Brad Farr said Thynne had engaged in “appallingly bad behaviour” and domestic violence was not tolerated in a civilised society
Thynne was sentenced to three years in prison and a parole release date of June 19 with time already served.
