Bekker was producer and co-presenter of the 3pm to 6pm afternoon drive show with personality, Maurice Carpede.
"I've had so much fun at Smile and the listeners have been great to me," said Bekker. "But, it's time to move on and I'm eager to see what opportunities await me."
Bekker's still deciding on her next media move, but you'll still hear her voice-over work and see her on KykNet Musiek's JAM on Sunday nights.
