When she was fifteen, she wanted to be an actress, decided her real name of Abigail "wasn't showbizzy enough", and told everyone to call her Chantelle. She started modelling clothes in Henrik's, and then landed small parts in soap operas and a large role in a low-budget horror film. This led to her being noticed by a high-end fashion house, achieving her childhood ambition of being famous. When Ace returned to England, Chantelle initially disliked her as she did not make an effort to continue their friendship. However, they met in a pub in Perivale on a Friday, chatted all night, and made amends.

By 2020, Chantelle was thirty-seven years old and still working as a model. She went clubbing on weeknights and attracted a lot of young male fans, but sometimes wondered if she was too old for her lifestyle.

Chantelle used some of her earnings to set up an anti-knife crime initiative, and donating money to youth centres, skateboard parks and libraries, which Ace (now called Dorothy) admired her for. Dorothy invited Chantelle to join A Charitable Earth multiple times, but she declined. When Dorothy visited her, she had been hearing strange noises at night, and had noticed the large amount of rats that had suddenly appeared in the area, but had decided this were because of the food bins that had been left out. She was friends with Gina, who told her that Kim Fortune had been "poking about" too, which she told Dorothy.

Although she was famous, she bought a flat in the same block as her mother and grandmother, and stayed in the same area, which Dorothy admired, although she rarely woke up until after twelve o'clock. (PROSE: At Childhood's End)
