Abi Titmuss is taking legal action against the News of the World after police informed her that her phone may have been hacked.
The glamour model and actress came to prominence in 2003 when she was dating former TV host John Leslie, later launching her own modelling and presenting career.
She joins a number of other celebrities and well-known figures who have begun legal proceedings.
Abi, 35, has appointed lawyer Charlotte Harris of legal firm Mishcon De Reya, who is already representing Sky Andrew, Leslie Ash and Lee Chapman among others in their claims.
Her agent said: "We can confirm that Abi Titmuss is taking action against the News of the World following notification by the police that her phone was intercepted over a long period of time."
Abi became a familiar face as she supported Leslie when he was accused of rape. The case was dropped by prosecutors.
She went on to become a "lad's mag" favourite and has gone on to forge an acting career. She is currently in rehearsals for a leading role in Dusk Rings A Bell at the Edinburgh Festival in August.
