Dan Evans has admitted fiddling his expenses while working as a journalist by taking his girlfriend out for dinner, the hacking trial has heard.
During his fifth day on the stand at the Old Bailey , Evans was asked about claiming for a meal by misrepresenting it as a source.
He said: “He said: "It was part of our culture at the paper but I don't see what it's got to do with hacking phones."
Evans was being cross-examined by Coulson’s lawyer Timothy Langdale QC.
The court heard that Evans has already admitted conspiracy to hack phones at the Sunday Mirror between February 2003 and January 2005, and the same offence at the News of the World between April 2004 and June 2010.
He also pleaded guilty to conspiracy to commit misconduct in public office between January 2008 and June 2010, and perverting the course of justice by giving a false statement in High Court proceedings.
Earlier, the trial heard a series of emails between other staff at the News of the World, including Coulson, discussing information from two sources close to Law talking to another journalist.
Transcripts from interviews read to the court exposed information from the sources described as One and Two.
Source One told the News of the World that he first saw Miller with Craig at the London restaurant, The Ivy, and Miller was "panicking" that the press would make something out of it.
The second time, Source One said they were at a house in Notting Hill. Craig left and drove off while Miller hid behind the door, the court heard.
Source Two told the News of the World that Miller was just "keeping Jude dangling" while "going onto her next victim".
Source Two claimed that Miller was "clingy" and a bit of a "stalker" so would call both Law and Craig several times an hour.
The source said: "They (Miller and Craig) are constantly on the phone with each other. She is always texting and ringing."
The source asked a News of the World journalist if he had access to their phones, and the response was "No, no, no, that would be illegal,” Langdale said.
The source told the News of the World journalist that Miller had moved out and "fled the country", adding: "She not a nice girl, she's not a goody two shoes."
The source goes on to suggest that Law wanted the story about the split back- dated to look like Miller "cheated first".
Langdale put it to Evans that the information came from these sources, not a voicemail, but the witness disagreed.
Former News of the World editor Andy Coulson 46, a PR consultant of Charing, Kent, denies conspiring to hack phones and conspiring to commit misconduct in a public office.
All seven defendants, including former Sun and NotW editor Rebekah Brooks, deny all the charges against them.
