Mark Pasetsky, editor of the US version of OK! magazine, is being replaced by Richard Spencer, the former chief editor of Bauer's In Touch Weekly.
Pasetsky, who had taken over the top editorial role only last year, will retain his previous position as managing editor, and will be reporting to Spencer.
Commenting on the appointment in a press release, Paul Ashford, group editorial director of the title's British owner Northern and Shell, said that Spencer "clearly brings the kind of experience that can build on the progress we've made in our first five years and push our editorial product to the next level."
Before leaving as chief editor of In Touch in January this year, Spencer had been creator and chief editor at Twist Magazine, J-14, Life Story Magazine and Soap Opera Update.
Meanwhile, Folio reports that the US publisher of OK! has rejected claims made in media reports that that the title - which was launched into the country in 2005 - is losing more than $700,000 per issue.
OK! magazine claims a readership of nearly 30 million for its 21 editions worldwide.
