The ex-EastEnders star's agent confirmed the sad news at the weekend and Danniella, 40, posted an emotional message on Twitter to her lover Tom saying: 'Thank u for just being u. Always putting me 1st & wiping my tears away x so blessed 2 call u mine x Love u Tommy xx '
Danniella and boxer/personal trainer Tom, 24, have had a whirlwind romance after meeting just three months ago, after Daniella split with her husband of 12 years.
They got engaged within weeks of meeting each other and soon a delighted Danniella - already a mum to Kai,17, and Jody, 12 - announced she was expecting.
When we met Danniella two weeks ago, she was over the moon at her unexpected pregnancy and after a tough year in which her once rock-solid marriage broke down and her house was burgled, her happiness was evident.
She was so looking forward to becoming a mum again at the age of 40 and was full of optimism.
That interview is published in this week's magazine which went to press before Danniella lost her baby on Friday night.
Our thoughts are with both Danni and Tom at this sad time.
