Heather Mills has made several complaints to the press watchdog about inaccurate reporting and invasion of privacy in three national newspapers.
The former wife of Sir Paul McCartney lodged her grievances against the Daily Express, Daily Mail and The Sun with the Press Complaints Commission.
A PCC spokesman confirmed it had received "complaints about various issues including privacy and accuracy."
An investigation has been launched, and will take up to 35 days to complete.
'Inconsistent and inaccurate'
Mills also complained about local newspaper London Lite.
There were no further details about the nature of her complaints.
In May, Sir Paul and Mills ended their six-year marriage in London's High Court.
During the divorce proceedings, the model and charity campaigner was heavily criticised in the press, particularly after the judge said her evidence had been "inconsistent, inaccurate" and "less than candid".
She was eventually awarded a £24.3m settlement.
