Congratulations to Sarah and Lachlan Murdoch, both 37, who welcomed 3.28 kg daughter Aerin Elisabeth Murdoch at 6.27 PM on April 12.

The couple already have sons Kalan, 5, and Aidan, 3.

The National Breast Cancer Foundation patron revealed her third pregnancy last October.

As to whether this will be the last addition to this branch of the Murdoch dynasty, Murdoch said last year, "I've always wanted four, but I'm getting a bit old now so it will be whatever we're lucky enough to have."

The birth was announced by a friend on Twitter.
