Brittain Stone, a veteran of Us Weekly for 14 years, is leaving his post. Adweek reports that Stone will be replaced by¬†Jennifer Halper, formerly the magazine’s Deputy Photo Editor.

It’s not known why Stone left, but sources told Adweek that he didn’t get along with Mike Steele, Us Weekly’s Editor-in-Chief. Steele was just given a contract extension by Jann Wenner in October.
