You're not wrong there and it does sound like her but I really hope the producers have cast their net a bit wider than that. (No offence to the girl - she's actually done really well for herself!)
I wonder if Phoebe Dynevor would do TMS. She's probably way too cool for this kind of thing but the clues fit soooo well and the fact that her Mum is ITV through and through and doing DOI might swing it. I'm plumping for Phoebe atm, for Firework....at least til I change my mind which happens ALL the time
