Heart London breakfast co-presenter Harriet Scott is going national to cover Emma Bunton's weekend show while the former Spice Girl is on maternity leave.
She'll look after the Saturday afternoon slot over the summer, starting from this weekend.
Emma Bunton announced on air earlier this year that she was expecting a baby boy – her second child with fiancee Jade Jones. The baby is due next month and she's expected to return to Heart later in the year.
The 4-7pm Saturday show airs across all Heart stations in the UK, and has an audience close to a million listeners.
Harriet told RadioToday.co.uk: "I'm really looking forward to covering Emma's show. She has many loyal listeners and I will do my best to keep them entertained until her return. The Saturday Show is such a fun show to do because it's slap-bang in the middle of the weekend, gearing up for Saturday night. It's going to be a summer of fun!"
