Sarah Abo marked the impending arrival of her first child with a stylish baby shower.

The Today show co-host was surrounded by close friends and family in her home city of Melbourne.

The 40-year-old is expecting a baby boy with her husband of 13 years, Cyrus Moran, and announced the pregnancy on March 11.

The intimate baby shower took place at Carlton Wine Room, with Sarah reposting a series of photos from the event to her Instagram stories.

The mum-to-be looked radiant in a flowing white long-sleeved gown, teamed with black heeled boots and bold silver jewellery.

The semi-sheer dress highlighted her growing baby bump, which she proudly cradled while posing alongside her inner circle.

White floral arrangements adorned the venue, while one sweet detail stole the spotlight: a baby shower cake decorated with white and pastel blue icing in honour of her soon-to-arrive son.

The round cake was decorated with tiny blue hearts and read ‘oh boy!’ in icing.

Today’s cultural correspondent and media personality, Jack Charles, was among the small number of guests invited.

Earlier this year, Sarah held back tears while revealing the exciting baby news live on-air.

She admitted it had been a difficult journey to get pregnant after losing a baby last year.

“It’s not as easy as you, I suppose, sometimes think that pregnancy will be,” she said.

“It has been a bit of a bumpy ride, but here we are, and yes, it’s getting harder to hide.”

The TV host didn’t say what name they had settled on just yet, but she and Cyrus had nicknamed him CJ for the time being.

Who will replace Sarah Abo on the Today show?

Channel 9 is under pressure to find a replacement for Sarah as she gets closer to going on maternity leave.

The TV presenter is in her third trimester and joked on the Today set last week that it was getting hard to breathe at this stage of pregnancy.

A date has not been set for when she will leave her hosting duties and start maternity leave – nor has a replacement been announced.

However, Nine insiders told news.com.au that Today newsreader Jayne Azzopardi had emerged as a frontrunner as Today Extra co-host Sylvia Jeffreys commands a “higher salary” and executives are concerned about her dynamics with Karl Stefanovic, which is also her brother-in-law.

Jayne has been with the Nine Network since 2009 and has done virtually every job on the breakfast TV beat, from Weekend Today co-host to political reporter.

Media commentator Andrew Mercado told Yahoo Lifestyle that it was very likely Nine would look internally for Sarah’s temporary replacement.
