Christina and Sadie share a very close bond. For Christina, Sadie’s birth was especially meaningful.
In 2008, Christina was diagnosed with breast cancer, which became a major focus of her life at the time.
The experience had a deep impact on her both physically and emotionally.
Christina has shared that she struggled with her feelings about her chest, but this changed when she held Sadie against her bare chest for the first time.
She has also expressed that Sadie’s arrival brought emotional and spiritual healing to her.
In an interview, Christina said that Sadie “opened a whole new part of her soul.”
Because of their close connection, Christina always made sure that Sadie stayed with her, even while she was working.
She only accepted jobs if Sadie could come along.
The producers of the show Up All Night, where Christina was a lead character and Martyn worked as a composer, set up a space on set for Sadie to be with her mom.
The space had Sadie’s toys, a crib, and a place for naps.

Sadie Grace Lenoble Loves Playing Piano
As Sadie grows up, her interests have expanded.
Currently, she enjoys playing the piano and has a passion for music.
She has expressed her desire to pursue music and become a professional singer when she gets older.
While Christina and Martyn support her musical dreams, they have set one condition if she wants to act.
No Acting Before 18 For Sadie
If Sadie chooses to become an actress, she must wait until she turns 18. Christina has set this rule for her daughter.
Interestingly, Christina started acting when she was just three months old and again at the age of 12.
Christina created the age rule after noticing Sadie learning different accents.
She does not mind Sadie taking acting classes before turning 18.
Christina’s reason for making Sadie wait is her strong belief in the value of education.
She believes that success in acting is rare, and having a good education will provide Sadie with other career choices if acting does not work out.
Sadie’s Risk of BRCA1 Gene Mutation
Sadie has a high risk of inheriting her mother’s BRCA1 gene mutation.
This mutation increases the chances of developing certain types of cancer.
Christina, who carries this gene, was diagnosed with breast cancer in 2008. More recently, in 2021, she was diagnosed with Multiple Sclerosis (MS).
Due to Sadie’s high risk of carrying the BRCA1 mutation, Christina has promoted a healthy and organic lifestyle at home.
As a result, Sadie stopped eating meat in 2017 and now follows a mostly vegan diet.
Her home environment has shaped her lifestyle, where she only eats organic and vegetarian food.
