Jill Scott performs live at Wingate Field as part of the Martin Luther King Jr concert series, New York City, USA - 11.08.08

The singer/actress plays a Botswana-based sleuth and thought she was doing an amazing job until locals started raising their eyebrows at her accent.

She explains, "I was dialect-coaching with the wrong person. I don't know how many people would notice the subtle nuances, but the people from Botswana were like, 'Uh oh!'"

Scott has since discovered her voice coach hailed from Botswana's neighbour Zimbabwe - and was honing her accent to his native dialect.
