Julie Gayet, the actress linked to French President Francois Hollande, is suing Closer magazine that published photos of their alleged affair.
Julie Gayet, 41, initiated proceedings against Closer for breach of privacy, the magazine told AFP news agency.
Francois Hollande himself said last week he was considering suing the magazine.
The photos plunged the presidency into a crisis which saw Francois Hollande’s official partner, Valerie Trierweiler, taken to hospital.
Julie Gayet is seeking 50,000 euros ($68,000) in damages and 4,000 euros in legal costs from the magazine.
If Julie Gayet wins, Closer magazine will have to publish the legal verdict on its cover page, AFP reports.
