A French nanny described having fears like a "little spike" to the heart before she was killed and her body thrown on a bonfire, a court heard.
Sophie Lionnet, 21, was allegedly murdered by her employers Sabrina Kouider and Ouissem Medouni after they became fixated that she was in league with a former pop star.
Before her death, they forced her to confess to outlandish claims against Kouider's ex-boyfriend Mark Walton, who founded Irish band Boyzone, the Old Bailey has heard.
In French and halting English, Miss Lionnet wrote about supposed meetings with the Pop Idol Vietnam judge in which she claimed he indecently assaulted her.
Amid the rambling account, she also told of missing her friends and family and being "scared" and "lost", the court heard.
Prosecutor Richard Horwell QC read out the handwritten pages detailing how LA-based Mr Walton promised to use his contacts to get her a job in films.
She wrote that she liked dance, movies and music, and was a fan of actors Tom Cruise and Sylvester Stallone.
According to the notes, Mr Walton asked if she wanted to be "famous and have a lot of money" like her idols but she told him "you don't need a lot of money to be happy".
She described secret meetings in London in which Mr Walton demanded to know about Kouider's life.
On one alleged meeting, she wrote: "I'm really scared this day more than before. My heart. I feel this little spike, I mean like when you go to have a tattoo. I feel like this in my heart."
She claimed he put his hand on her chest and "started to touch my private place" before she managed to get away.
She wrote: "I was afraid, scared, lost. I don't know what to do. When I was going home I was like keeping the smile like nothing happen."
She went on: "I just want to go back to my family. I promised them I'm going to come back soon because I miss them and they miss me."
The court has heard that none of the allegations against Mr Walton were true.
Kouider, 35, and Medouni, 40, of Wimbledon, south west London, have admitted perverting the course of justice but deny murdering Miss Lionnet in September last year.
