U2 guitarist Adam Clayton never saw his former PA accused of stealing nearly €3m from him "swanning around in a limo" or "wearing shoes with the red soles".
However he told the trial of Carol Hawkins that she wrote cheques from his account and put them into her own.
He has denied Hawkins (48), of Lower Rathmines Road, Dublin purchased items for him in her name to protect his privacy and anonymity.
Mr Clayton said: "The fact is she wrote cheques from my accounts and put them in her accounts. She was using my accounts to pay her bills."
Hawkins has pleaded not guilty at Dublin Circuit Criminal Court to 181 counts of theft from two of Mr Clayton's Bank of Ireland accounts over a four year period from 2004 to 2008. The alleged thefts totalled €2,869,274
Under cross-examination by defence counsel Ken Fogarty, Mr Clayton denied that Hawkins spent the €2.8m for his benefit.
Defence counsel suggested privacy was the reason why it was Hawkins name on the lease for the apartment at Taylor's Hill in 2006 which was being rented by her and her family while renovations were taking place at Mr Clayton's Danesmoate estate.
Mr Fogarty put it to Mr Clayton: "You would prefer not to have every Tom, Dick and Harry knowing things about you, bar he lives there."
"That would be fair," Mr Clayton replied.
Mr Clayton agreed it was him who was paying the rent on behalf of Hawkins as this was part of the salary deal they agreed on. "But there was no necessity for her to pay for things for me in her own name," said Mr Clayton.
Mr Fogarty asked the witness if he accepted that he lived in a world that "the rest of us", could only observe.
Mr Clayton said he lives a perfectly normal life when he is not working and he has "done shopping" for himself.
When it was put to him that some people live in a more rarefied atmosphere than others, Mr Clayton replied "only when I'm working".
"We all live in the same world," he added.
He agreed with counsel he had never seen the accused "swanning around in a limo," or seen her "wearing shoes with the red soles", referring to Christian Louboutin shoes which were purchased on Ms Hawkins credit card with money allegedly transferred from Mr Clayton's bank account.
He also said he did not give Hawkins permission to spend his money educating her children, Joe and Eleanor. He said he had hired Hawkins and her husband John to work for him and how they educated their children was not his concern.
He said he was not concerned about how Mr Hawkins was paying for the upkeep of the horse he loaned him €20,000 to purchase. He explained Mr Hawkins told him he could not get a loan from the bank.
"They were trusted and I lent the money."
The trial continues.
