A cleaner from Greenwich in England has admitted stealing cheques from illusionist Derren Brown.
Rocio Pavon-Navarrete took the two signed cheques from Brown's home while he was away.
She broke down in tears after pleading guilty to the offence at Southwark Crown Court.
Judge David Higgins adjourned her case until October 11 for pre-sentence reports.
He said: "Whilst I have adjourned for a pre-sentence report, indeed a high probability remains that she will be sentenced to immediate custody given that which is obviously the grossest breach of confidence."
He added: "I wish her to have no illusions about what the future is likely to hold given the very serious criminality to which she has pleaded guilty."
Pavon-Navarrete (aged 47) of Bardsley Lane, Greenwich, was bailed until the sentencing hearing.
Co-accused Bernard Ayanbanjo will go on trial over allegations he received the cheques - worth £21,550.35 (€26,918.40) and £11,500 (€14,365) - from Pavon-Navarrete and paid them into his own bank account between October and December 2010.
Ayanbanjo (aged 48) of Waverley Road, Woolwich, has pleaded not guilty to two charges of fraud.
Brown sat in the public gallery as the jury was sworn in for Ayanbanjo's trial.
