British-born Sesay, 37, who spent her childhood in Sierra Leone, opted for a career in the media while in her final year at Trinity College, Cambridge.
However, after university, she ditched her Hollywood dreams to work as an intern on the BBC talk show Kilroy where she organised guests.
“After that I did a host of different things [including being a sports presenter on Sky Sports]. But I wanted to do hard news, so I sent CNN a tape. They invited me to an interview and a screen test before getting the job.
“News is always what keeps me happiest. I have always been involved in multiple projects to keep me from getting bored,” she said in a recent interview in Lusaka, Zambia.
