Time Inc. has let InStyle Publisher Nina Lawrence go less than six months after the company hired her, a Time Inc. spokeswoman confirmed.

A successor has not been named, but a person familiar with the matter said Steven DeLuca, who is publisher of InStyle sibling title Departures, will serve as interim publisher in addition to his duties at Departures. Instyle Editorial Director Ariel Foxman remains in his position, this person added.

The Time Inc. spokeswoman declined to elaborate on a possible successor to Ms. Lawrence or the reason for her exit, which happened on Tuesday.

Ms. Lawrence did not immediately respond to an email or a LinkedIn message from Ad Age.

Her departure comes as InStyle parent company Time Inc. readies its pitch to advertisers on Thursday as part of the annual digital NewFront presentations, where media companies show off their digital-video wares.

It also comes as Time Inc. invests in InStyle's digital efforts. According to Time Inc.'s annual report, InStyle is the cornerstone of an effort to bring the company's fashion and beauty assets onto a single digital platform for content, services and commerce. Ms. Lawrence's hiring in November 2014 was seen as a step in that direction and heralded as a win for Time Inc., the nation's largest magazine publisher, which is trying to recast its print brands for the digital age.

Before joining Time Inc., Lawrence was VP of global marketing-advertising sales at The Wall Street Journal, where she led marketing and business development for newspapers, magazines, websites, mobile devices, video and live events. She also oversaw WSJ Custom Studios, which created content-marketing programs for advertisers.

Prior to the Journal, she worked at Conde Nast, including seven years as VP-publisher of W.
