Snapped holding her growing bump, the beloved presenter could be seen looking happier than ever in her opulent ensemble.
Emily opted for a floor-length black gown with a plunging neckline, simple black shoes and minimalistic jewellery.
She complemented the stylish look with her blonde locks curled into an effortless style and glamorous, barely-there makeup.
The Inbetweeners actress, 34, is expecting her first child with scientist Dr Alistair Garner, which she announced back in December.
She has only been pictured publicly with Dr Alistair on one occasion – in September of last year – and has shared very little details about the romance.
The Sun previously revealed that Alistair is the son of her late uncle – Dr Stephen Garner – who married Emily’s aunt Jane Robbins in 1994.
An insider said: “Emily and Alistair consider themselves more family friends but they are cousins who aren’t related by blood.
“They grew up together and have always got on really well, but last year they started to get closer.
“It has been a really natural evolution of their friendship and they both have strong feelings for each other.
“Emily and Alistair were thrilled when they found out they were expecting and are really looking forward to becoming parents.
“Their respective families are totally supportive and have told them they think they’re a lovely couple.
“It is a really exciting time for them.”
Emily is already five months pregnant and announced the news on social media, gushing: “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. 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.
