Isabelle Thomas was 'adored, bright and charming', says grief-stricken family of her Killers of the Flower Moon producer husband after her suicide at Hotel Angeleno

A British aristocrat and wife of a top Hollywood producer who committed suicide on Monday was a ‘forever friend’, ‘adored, bright and charming’, her sister-in-law told DailyMail.com.

Isabelle Thomas, 39, fell from a high balcony of Hotel Angeleno in Los Angeles on Monday evening, in what authorities are describing as a suicide.

The mother of two leaves behind her husband, Killers of the Flower Moon producer Bradley Thomas, 58, and her two young daughters.

Thomas’ sister, Diana O’Donnell, told DailyMail.com that Bradley’s mother and niece had flown to LA to look after him and she would soon follow, while his four male friends are ‘waking the kids up in the morning and feeding them breakfast and reading them stories’ as he grieves.

‘It was really easy with her. She just felt like a forever person in my life, a forever friend, and a wonderful sister-in-law. We’re all really sad and broken. It’s just such a horrific loss to all of us,’ she said.

The aristocrat's suicide was described by family members as a 'horrific loss' but said her husband is being supported by his mother and friends

Izzy, as she was known to her friends, was the daughter of Sir Henry Lawrence, 7th Baronet of Lucknow and his ex-wife Penelope Nunan.

She met Bradley in LA while working as a documentarian and married in 2018.

Diana, 59, said she knew what her brother was going through, as she lost her husband to suicide 20 years ago.

‘It’s hit our family more than once,’ she said. ‘We don't realize how vulnerable and how fragile we are. There's no trying to understand it. It's just chemical imbalance, or whatever you want to call it.

‘It’s really hard being a single parent. He’s extremely lucky because he’s very well-liked and loved by so many.

‘We're very fortunate to have this circle of friends around us and family.

‘I had the luxury of having things very quiet, not so public. I worry about these little girls growing up one day and Googling their mom.

‘These little girls are gonna grow up without their mom and have a lot of questions and a lot of sadness, because mom's not there to watch them grow and celebrate all their milestones that they're going to have in their life.’

The Thomas family have suffered a succession of devastating losses, including their father Charlie (pictured) who died of pancreatic cancer in 2022 age 81.

Diana was full of praise for her late sister-in-law.

‘We adored Izzy, she was bright. She was charming. She was just always lovely. She never had anything bad to say about anyone,’ the Maryland native said.

‘Izzy was just happy to have a piece of you, no matter what you gave her. She was really easy and simple in that regard, she never put demands on anyone.’

Bradley’s sister declined to comment on Isabelle’s mental health, saying ‘her health situation was private’, but added that ‘obviously someone is struggling mentally, to be able to go to the extreme of taking their own life.’

The Thomas family have suffered a succession of devastating losses, after Diana’s husband’s suicide, her and Bradley’s young aunt who was raised like a sibling to them but died of lung cancer in recent years, and their father Charlie who died of pancreatic cancer in 2022 age 81.

Bradley’s older sister is intensely proud of her brother’s achievements, listing on Facebook the Oscar Best Picture nomination for Killers of the Blood Moon and its lead Leonardo DiCaprio’s Golden Globe nomination for Best Actor in a drama.

Bradley has also produced hit movies There's Something About Mary and Dumb and Dumber.

Diana posted lovingly about her late sister-in-law, sharing Isabelle’s wedding photos in 2018 and a photo of her in March 2021 with her two baby daughters.

O'Donnell declined to comment on Isabelle’s mental health, saying ‘her health situation was private’, but added that ‘obviously someone is struggling mentally, to be able to go to the extreme of taking their own life.’
