But we wonder whether she consulted Coco, the agency dog.
Johnson led the buyout of the agency in 1998 at the age of 25, but from 7 June she will spend a week in 'deepest, darkest Sussex' with new 'husband' Tim and her four new children, all under the age of five.
Meanwhile, housewife Emma will take over Johnson's everyday responsibilities at Strawberry that will include taking briefs, developing PR strategies and presenting to clients.
But perhaps her biggest job will be walking Coco - the chocolate brown labrador that, more often than not, can be found asleep on the agency sofa - to work every day.
The programme is set to air later in the summer, when we'll see whether four toddlers are more demanding than a labrador ... not to mention the clients.
