Sam made the decision to share the first picture of her baby daughter on her own accord, as a source exclusively told MailOnline: 'A number of publications made significant financial proposals for the exclusive first images of her second child. 

'However Sam shunned all offers and decided to share the first pictures of her new born on her Instagram page..'

Speaking to MailOnline a matter of weeks before confirming her pregnancy, Sam insisted the couple wanted a 'big family' - and that she was feeling 'broody' since becoming an aunt to her sister Billie's second son.

'We do want a big family, and when Billie had her second baby, Arthur, it made me broody,' she told MailOnline. 

'It made me all, "Ohhh I want a newborn!" But I think there should be a three or four year age gap between my children. Plus we are really just enjoying baby Paul right now!' 

The family are preparing to air the third series of their reality show The Mummy Diaries, which will document every detail of Sam's second pregnancy.

The reality star and Paul - who have been together for three years - welcomed their first child, baby Paul, in December 2015.
