‘Congratulations on the new addition!! I was looking at the blue dress picture thinking is she pregnant still?? Surely not with that figure! Think it’s great you let your follows know what’s going on and still keeping your children private,’ one Instagram user wrote.

Another added: ‘Oh my goodness!! I’ve been wondering when you were due. Congratulations!!’

Luisa – who announced she was expecting back in June, just 10 months after the birth of her second child – went on to explain a little more about why she had decided to break her silence.

‘I announced pregnancy because I was papped twice without me knowing and everyone said how fat I had gotten, it really upset me knowing I was 5 months pregnant so chose to announce pregnancy,’ she told a fan in the comments section.

‘Have only announced birth now because obvs bump is gone and ppl have been messaging thinking something bad happened to the baby. Xx’

The former Celebrity Big Brother star has regularly been posting photos on Instagram since Clementine’s birth with no mention of the baby until now, leading to countless questions from her fans about whether she’d had the tot or not.

Now the news is out there’s just one thing left to say – congratulations Luisa and family on your new addition!
