Australian Olympic champion Libby Trickett has announced she is expecting her fifth child with her husband Luke.

The swimmer, 39, took to Instagram on Friday to share her jovial baby news with her 76,000 followers, confirming that she is already around four months pregnant.

Sharing a photo of their ultrasound scan, she admitted that she and Luke were both ‘excited’ and ‘terrified’ when they revealed they were about to welcome another child.

The couple already have four children: daughters Poppy, eight, Edwina, five, and Bronte, three, and a son, Alfred, 18 months.

They have yet to discover the gender of their fifth child and Libby shared her excitement about her growing family in her heartwarming post.

She said: ‘Luke and I are absolutely thrilled (and a little terrified) to announce that we will be welcoming Baby Trickett 5.0 into the world this April!!

‘Poppy is already excited about having another baby, Eddie thinks it’s going to be a boy and Bronte thinks it’s going to be a little girl and Alfie keeps pointing at my stomach and saying ‘baby’ but really has no idea what’s in store for him. ‘

Libby was quickly flooded with congratulations from her famous friends and followers as they shared their joy with the happy couple.

Michelle Bridges commented on her post: “Congratulations,” while Grace Tame also left similar sentiments.

Author Rebecca Sparrow added, “The world needs more people who grew up in warm, loving homes. I’m so happy for all of you, Lib. You got this. And we all have you.”

Meanwhile, one user commented: ‘Yay! Congratulations Lib, such a fantastic mother.’

While another wrote: ‘Amazing!!!!!!! Big families are the best.”

Libby’s baby news comes just 18 months after she and Luke welcomed their fourth child together last May.

The Olympic gold medalist shared the happy news in a heartfelt post on Instagram at the time, posting photos of her cradling her newborn son in the hospital.

“He’s here,” the proud mother shared in her post. ‘The last piece of our family puzzle (this time in real life!).

“Alfred Sunny Trickett arrived at 9:09 a.m. on May 17. Every birth I’ve had has been extraordinary and this one was no different.

‘Calm, full of joy and laughter, I couldn’t have asked for a better way to meet our baby boy.’

The champion swimmer, who is already mum to three daughters, joked: ‘Alfie has no idea what he’s in for with his three big sisters and the girls are completely in love.’

She said Alfie was born via elective caesarean section, weighing 3.5kg and measuring 52cm in length.

Libby has previously opened up about her history with postpartum depression after welcoming her third child, Bronte, in 2020.

“I think when you go through a change like that in your life, it can always be quite scary,” she said.

“Especially for me, knowing that I’ve had a history of postpartum depression, and it’s certainly something we’re very aware of.”

When Poppy was just four months old, Libby said the extreme sleep deprivation caused her mental health to deteriorate.

The lack of sleep made her angry, and it got to the point where she started yelling at her daughter.

“It’s almost like I went on a mental break, and I just had a moment where I completely lost it with Poppy, I screamed at her,” she said.

‘The progression of the extreme sleep deprivation she put everyone through only exacerbated my mental health and my mental illness to a point where I became afraid of myself.

“I couldn’t imagine being an eight-month-old baby and being yelled at.”

Libby then decided she needed help and used her memoir, Beneath the Surface, to help other women understand the warning signs of the condition.

She took home the gold medal at the 2004, 2008 and 2012 Summer Olympics, and was the world record holder in the 100-meter short course freestyle.
