The 31-year-old actress can be seen putting her feet up, as she reclines in a knitted body con dress.

With a protective hand above her precious bump, the blonde beauty shows off her delicate engagement ring.

‘Last min bump cuddles before me and @rebeccagreen21 head out :) #blessthisbambino’ she captioned the snap.

Catherine is expecting her first child with fiancé, Tom Pitfield, and has been updating followers of her healthy eating plan while she is pregnant.

Just recently, Catherine tweeted that her baby was ‘obsessed with Kale chips :) good lad.’

This month Tyldesley defended her whirlwind romance with her personal trainer beau. Speaking to OK, she said: ‘No one’s been shocked at how quickly we’ve moved because people can see how happy we are.’

She added: ‘Three months in I knew. We never argue. He makes me laugh until I cry!’

Tom proposed to Catherine after just eight months of dating, while the pair where on holiday in Venice.

‘I couldn’t stop crying and said yes through my tears,’ she recalls.
