Glowing and growing! Heavily pregnant Jesinta Franklin shows off her baby bump in a billowing maxi dress as she goes for a stroll in Sydney

She will soon welcome her second child with husband Lance 'Buddy' Franklin. 

And on Tuesday, Jesinta Franklin (nee Campbell) showed off her growing baby bump as she went for a stroll in Sydney's eastern suburbs.

The 29-year-old, who is around 32 weeks pregnant, looked stunning in a billowing maxi dress by Aje, which retails for $456.

The soon-to-be mother-of-two appeared relaxed as she enjoyed the sunshine and pushed the couple's 11-month-old daughter, Tullulah, in a pram.

She kept a low profile with dark sunglasses covering her striking features - and her long brunette tresses were styled in a bun.

Jesinta teamed her designer outfit with gold hoops and Christian Dior sandals, which retail for about $1,200.  

The beauty will welcome her second child with her AFL superstar husband, 33, in late March.

She confirmed the couple were expecting another bundle of joy in an Instagram Live chat with supplement brand Vida Glow founder, Anna Lahey, on October 28.

'Yes, yes nearly half way through. It was a very big surprise for us. Tullulah will be getting a sibling at the end of March next year so she will have just turned one,' Jesinta said. 

'So I'll have a 13-month and a newborn, which was very daunting at first. I found out a week after Buddy went into the hub, which was all just a lot to deal with at once, but yeah, very blessed.

'It was very hard to conceive the first time with Tullulah, and for this (pregnancy) to be such an unplanned surprise is a blessing.' 

It will be the second child for the couple, who tied the knot in the Blue Mountains in November 2016 and will celebrate Tullulah's first birthday on February 25.
