The actress Sienna Miller will give evidence in the hacking trial today.
Miller is due to speak via video link from the United States for up to two hours, the Old Bailey jury has been told.
The Layer Cake star was the subject of a story allegedly produced with help from the "dark arts" of hacking at the News of the World in 2006.
Earlier this week, the trial heard from her former boyfriend Jude Law who spoke about the intense media interest in them when they were a couple.
The trial also heard how Dan Evans, then a journalist at the newspaper, hacked into a voicemail from her to James Bond actor Daniel Craig, sparking a story alleging they were having an affair.
The editor at the time, Andy Coulson, 46, from Charing, Kent, is among those on trial for conspiring to hack phones and conspiring to commit misconduct in a public office.
All seven defendants in the case deny the charges against them.
