Wikipedia Biography / Profile Background

Introduction :

The spitting image of her mother, the young Cosima Thomasina Diamond is the eldest child of TV Chef & UK’s Domestic Goddess Nigella Lawson & her late husband, journalist and broadcaster, John Diamond.
Since 2013, Cosmina has repeatedly appeared in the media due to the very public and messy divorce of her mother & stepfather Charles Saatchi.

Personal Life : Parents, Family and Education

Cosima was born in January 1994 in Hammersmith, London.
She grew up with her parents and younger brother Bruno Paul Dimond.
On March 2, 2001, aged just 7, Cosima lost her father to throat cancer. Within two years, she had gained a new father figure, Charles Saatchi & a step-sister Phoebe Saatchi.
Along with her mother and brother, Cosima lived in her stepfather’s $22.5 million Chelsea Mansion, London.
Education : Cosmina attended the Latymer Upper School. The West London based private school charged £16,500 in yearly tuition.
Miss Diamond grew up surrounded by designer label clothes, VIP tickets & allegedly ran up a taxi bill £2,109 on vacation in Los Angeles.
Cosmina earned the nickname Mimi (Mini-Me) from the stark resemblance she bares to her mother.

TV & Media Appearances :

Aside from the unpleasant shots taken by paparazzi throughout her family’s crisis, Cosima has also appeared in her mother’s TV show “A Taste of My Life” in 2008 and “Nigellas Kitchen” in 2010.

Interesting Facts, Gossip and Trivia :

During her mother’s divorce, Saatchi publicly accused Nigella of “trashing her daughter’s life by allowing her to take drugs.”
The Grillo Sisters, who were simultaneously sacked by Lawson, also claimed that “Nigella lets her children smoke weed.”
While Nigella had confessed to regularly using class B drugs for at least a decade. Coincidently, that is also the duration of her marriage to Saatchi, her daughter Cosmina has made no comment on her personal drug use.
In recent years, Cosima’s quick temper has given her a bad reputation. On March 28, 2017, she was caught on camera flipping the middle finger to Nigella’s paparazzi followers.

Height, Style & Body Details :

Cosima has been distinguished for her smart fashion sense.
She is friends with model Lillie Rage & has posed before the camera once herself.
Once photographed returning from a family holiday to Spain, she pulled off a brave outfit of jeans, loafers, a pastel blue coat, and 90’s choker.
On a separate occasion, she was spotted wearing a mid-length trench coat, black romper and dress shoes, finishing the ensemble with her long black curls.
With her Italian features, steely gaze & daring wardrobe combinations she could become the next big style icon.
The young beauty has featured in ‘Ladies of London’ for W Magazine 2014.
She has posed with models, Cara Delevingne, Adwoa Aboah, Sam Rollinson, Cora Corre, Will Heard and Danny Brady, sporting tight jeans and jacket in a London park.
