Inbetweeners star Emily Atack, who was previously a finalist on I’m A Celebrity… Get Me Out Of Here! is pregnant with her first child. The ITV star has said she has “never been so happy”, as she is expecting a baby with her boyfriend Dr Alistair Garner.

The actress 34, is five months pregnant and expecting her first child in April. It is understood that she and her nuclear scientist partner recently set up home together to prepare for their newborn’s arrival.

Emily took to Instagram this evening to share her happy news in view of her 1.9 million followers. The star could be seen beaming from ear to ear as she showed off her blossoming baby bump in a black-and-white photograph.

She captioned the snap: “Hello Everyone, it’s been a little while but I’m back with some news. I’m delighted to share with you all that we’re having a baby!!

“I’ve never been so happy and utterly terrified at the same time. Please go easy on me,” she added with a heart emoji.

“Every day is mixed with thrill, fear, joy, hysteria, topped off with a lot of vomiting – a bit like when you’ve just stepped off of the Oblivion at Alton Towers on a hangover.

“I’ve got to know my body on such an insane level,” she added. “It’s made me appreciate the one I’ve been given SO much, I’m doing my absolute best to make it a home for the little squid I’m growing.

“We can already sense the baby is reclined on a mattress of peanut butter and jam sandwiches in there, demanding more chocolate buttons.

“I’m so happy to be writing all of this to you all. You’ve always stuck by me through the years, do stick around to watch me enter my mum era. Christ. Let’s go.” (sic)

A source told the Sun that Emily is “over the moon” with her pregnancy and that her actress mum Kate Robbins “can’t wait to be a grandma”.

The source said: “Emily is delighted by the happy news and has been pleased to tell family and close friends about her little one on the way.

“It’s the perfect end to her year and she feels over the moon. Emily is more than ready to be a mum and it is something she has dreamed of her whole life.

“Her relationship with Alistair has gone from strength to strength and they’ve moved into together. Family is everything to her — she comes from a big one herself and is really close to all her siblings — so she can’t wait to start one of her own.

“They’ve all rallied around her and delighted in the joyous occasion,” the source added.

They continued: “Emily has been taking some time to herself and been quieter than normal on social media and focusing on her well-being and enjoying this special and magical time.

“She’s excited about next year and starting a new chapter in her life.”
