'Are you even pregnant?' Sam Faiers SHOCKS fans with new baby bump picture

Sam Faiers has shocked fans with her latest 'bump selfie', which left many struggling to believe she's already over half way through her pregnancy.

The reality TV star recently confirmed that she's expecting her second child with partner Paul Knightley.

But the 26-year-old left fans surprised by her latest baby bump update on Instagram, as she revealed she's already over the half way mark in her pregnancy.

Posting a mirror selfie in black underwear with her bump in full display, Sam wrote in the caption: 'Over half way 🤰🏽💁🏽 #littlebump #bumpselfie this pregnancy is going soo quick. 😌 '

Fans of the celeb mum were surprised at how slim she looks for how far along she is.

One commented: 'Are you even pregnant??', while another said: 'What the??! I thought you were 3 months pregnant!! I'm a whale compare to you and I'm just on 20 weeks. How do you stay sooooo slim?'

Many were comparing their own bumps with Sam's, saying theirs look so much bigger: 'wish I looked like this right now 🙈 over half way!!', one wrote.

Another commented: 'How is it possible that you look so amazing. I look so crappy whilst pregnant.'

The Only Way is Essex star announced the happy news last week on her Instagram account, sharing a snap of herself holding the couple's son, Paul, and showing off her growing bump.

'Words can't describe how excited we are to meet you baby 👶❤ We love you soo much already. #babynumber2 #2under2,' she wrote alongside the sweet picture.

Fans were quick to congratulate Sam and Paul on their lovely reveal, with one writing: 'Aww congratulations Sam. Love the baby diaries and can't wait to see your journey with this baby'.

'I knew it!!!!' another exclaimed. 'you are making me want another one 😭 congrats to you and Paul and can't wait to see baby P be a big brother ❤️❤️❤️'

Sam and Paul have been dating since 2014 after meeting at a restaurant in Chigwell, and confirmed that they were expecting their first child together in August of the following year.

'We were both really excited and happy,' she said to OK! magazine at the time. 'It was like a nervous excitement and a shock – it took a while for it to sink in. It was something that we wanted.'

'We spoke about it for a quite a bit and then it just happened. It was instant,' Paul agreed.

In December 2015, the pair welcomed baby Paul Tony, and have since been documenting their parenting journey on Sam's ITVBe series, The Baby Diaries and The Mummy Diaries.

The 26-year-old has made no secret of her desire to expand their family, most recently telling Closer magazine: 'I'd love to have more babies! Paul and I want five or six kids in the end.

'I want one soon as I think two years is a nice age gap.'
