The Inbetweeners actress, 34, will welcome her newborn in April 2024.

Having split from her Big Brother star and tree surgeon ex-boyfriend Liam McGough last year, Emily began seeing nuclear scientist Dr Alistair Garner earlier this year.

Her publicist has since confirmed the pair are in a relationship and they have reportedly set up home together as they prepare for the baby’s arrival.

So who is Emily’s boyfriend Alistair? Find out below.

The Inbetweeners star has announced she is pregnant and is ‘over the moon’ to be becoming a mother in the new year

Who is Emily Atack’s boyfriend Dr Alistair Garner?

Alistair describes himself on LinkedIn as a Materials scientist and electron microscopist specialising in nuclear and aerospace applications.

He attended the University of Manchester, where he studied for his PhD and Masters and also worked as a lecturer.

He received his undergraduate degree from Keele University and is thought to be in his mid-to-late 30s.

He is now believed to be a senior consultant for Core Materials at Jacobs – a large US company.

Emily and the hunky scientist have been pictured together just once over the course of their relationship and she has kept details of her boyfriend very private.

She didn’t confirm his identity in her pregnancy post – although her publicist has confirmed they are together – but still referenced him by her repeated use of ‘we’.

Announcing the happy news, she wrote on Instagram: ‘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.

He and Emily have only been pictured together in public once – as they enjoyed a drinks date together in London this September

‘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. 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.’

How long have they been together?

Emily and Alistair were first pictured getting cosy together in September in London.

She beamed as she walked down the streets of the capital with Alistair and they were spotted hand-in-hand as they settled in a cafe.

This is the only occasion they have been seen in public together and have kept their romance closely under wraps.

However, they hadn’t officially gone public with their relationship until the pregnancy announcement.

Despite this, a source has told The Sun that they have ‘moved in’ together as they prepare to welcome their first child.

Who has Emily dated in the past?

Emily had been single since she split with her former Big Brother star and tree surgeon ex-boyfriend, Liam McGough, last year.

They sparked rumours that they were back together in July after they spent the evening together with some pals.

However, pals of the pair said they were just good friends.

Liam was a housemate on the 2007 series of Big Brother when he finished in third place, losing out to winner Brian Belo.

Emily has previously been linked to a number of men, including singer Harry Styles, comedian and former Strictly Come Dancing contestant Seann Walsh, and footballer Jack Grealish.

The TV star and Manchester City footballer Jack were said to have enjoyed a secret six-week fling while he was still dating girlfriend Sasha Attwood – something the pair have vehemently denied.

What do we know about Emily’s pregnancy so far?

Emily revealed she is five months pregnant with her first child on Saturday and is expecting to welcome her child in April 2024.

A pal told The Sun: ‘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.’

Her celebrity pals were quick to take to the comments section of her Instagram post to share their congratulations with the star.

Denise Van Outen commented: ‘Congratulations xxx wonderful news,’ and Ashley Roberts said: ‘Aww congrats chica!!’

Kimberley Walsh wrote: ‘Ah amazing news! Huge congratulations!’ while Stacey Dooley also shared her well wishes.
