Last call for Showtime's 'Secret Diary'

Showtime said Friday (June 18) that it's picking up a fourth season of the series starring Billie Piper as a high-end prostitute -- but also that the new season will be its last. Production on the eight episodes is scheduled to begin in London in August; a premiere date hasn't been set.

The fourth season will follow Hannah/Belle (Piper), who's now a best-selling author, as she continues to waver between her career and the feelings she has for her best friend, Ben ( Iddo Goldberg). The final season will also feature Belle visiting New York.

Missing from Showtime's announcement is any mention of Ben ( James D'Arcy), Belle's editor and lover -- until the end of the last season, when they had a bad falling out. We asked a network rep if he'd be back but haven't heard yet.
