It’s always tough for a well-known face or name to keep their pregnancy under wraps – as Pippa O’Connor knows well.

Already a mum to toddler Ollie, yesterday the model and businesswoman announced she was expecting her second child.

Now at the 12-week mark – and previously eager to keep gossip to a minimum – Pippa revealed to SHEmazing! this afternoon that she has been forced to scale back on her social media activity.

"I haven't been using Snapchat or Instagram as much over the past few months because I didn't want people to talk or speculate," said Pippa.

"I found it hard because I've got so many events where I'm on stage. People had seen me going in and out of hospital and were starting to tweet me so I was like I better just say.

"Not that it's a massive deal, but you want to tell people yourself."

We caught up with the 30-year-old, who is now three months pregnant, at the Centra Christmas launch, and she revealed that she even kept her pregnancy a secret from her two-year-old son, Ollie.

"He repeats everything these days so I couldn't risk him saying something to the wrong person," she told us. 

Pippa admitted that the big news has only really hit her today. "It doesn't feel real until everyone knows because no one's saying it, today's the first day that it feels like, 'Oh I'm having a baby!' she laughed. 

The star doesn't know whether she is having a boy or a girl yet and is planning on keeping the sex a surprise until she is due, next May. She added that she will be "thankful as long as the baby is OK."

Ms O'Connor also revealed that she will have a packed house this Christmas as her family are all staying there for the festivities. "There will be about six adults and four children under four-years-old.. so it'll be a bit mental."

And when asked what she will be cooking, Pippa admitted that she will be heading straight to her nearest Centra.

"It have such a good range in store and there's so much to choose from… I will definitely be buying some of that gorgeous Christmas ham and brussel sprouts!"
