It is not clear when Lucy's due date (opens in new tab) is but she is expected to be past the 12th week of pregnancy.

The gender of the baby (opens in new tab) is also not known but this might become clearer nearer the time.

During her first pregnancy, she suffered from an unusual pregnancy side effect of orange breast milk.

The Thomas family recently shared a group snap taken from Halloween when they dressed as the Addam's family.

Back in September the couple had a scary time as parents, when their son Roman spent a week in intensive care unit. Ryan explained to fans the heartbreak he felt at the time.

He wrote, 'No words can explain how grateful we are to have our little boy home safe after spending nearly a week in intensive care.

'As parents it’s been one of the scariest times of our lives but with thanks to our amazing doctors & nurses we have king Roman back playing, smiling & more importantly eating, i would like to thank the @nhs and also @cosmic_charity who have been unbelievable, You both really are the real life superhero’s ❤️🙏🏼'
