"I have a podcast coming out in January with BBC Sounds which is really cool. It's a 12-episode podcast series based on the fact that I used to be a hairdresser, which is really fun!" the 31-year-old explained.
"Each Thursday I'll have a new guest joining me where we put the worlds to right around their style and key life moments. It's launching from 21 January on BBC sounds, so look out for 'Di's Salon', I can't wait for you to hear it!"
We can't wait to hear it either, Dianne!
