The proud couple took to their social media accounts to present the little sister to Ivy Mae to the world.
The star opener posed proudly for pictures with Indi Rae and Ivy Mae and posted them on his Instagram page.
"Candice and I welcomed beautiful little Indi Rae Warner into the world this morning. Mum was absolutely amazing," Warner wrote.
Warner flew home to Sydney after Tuesday's opening one-day international in Perth to prepare for the birth. He's been replaced in the Australian ODI squad by Usman Khawaja, but Shaun Marsh is expected to be Warner's replacement at the top of the order for the second match in Brisbane on Friday.
