Hold on to your hats kids. Creativity is reporting that Bob Isherwood is leaving the hallowed halls of Saatchi. Why? He says he needs to have ""more than one life in my lifetime."

"For the past 12 years I've been focused on the reinvention of Saatchi & Saatchi," he told Adage from his home in Miami. "Now I've reached a point where I feel a need to reinvent myself."

Saynora Bob. What will Roberts do without his partner in crime?

"For me this is personal," he said. "When you've had a relationship like this one, you don't want to jump into something new on the rebound. I'm going to let a little time pass, see in the new year, and then focus on what we should do next."
