Wonderful news for Penny Wong.

Congratulations are in order for Senator Penny Wong.

Senator Penny Wong and her partner Sophie Allouache just had a baby — and she’s gorgeous.

“Sophie and I are delighted to announce the arrival of Hannah, a sister to Alexandra,” Sen Wong wrote on Twitter this morning. “Everyone is doing well. ”

The Labor Senator for South Australia, 46, is normally fiercely protective of her family’s privacy — but posted an intimate photo of Alexandra Wong with baby Hannah to accompany the caption.

The photo, which shows dark-haired baby Hannah wrapped in a blanket as an adoring Alexandra gazes down at her new sister while sitting on a couch, appears to have been taken at home.

Senator Wong is now a proud mother of two.

She previously told Adelaide Now of Alexandra: “I get no sleep but it’s not as bad for me as for (partner) Sophie, so I can’t complain.

“She gets so much joy out of going for a walk or going for a swim or (being) in the garden looking at the plants and that makes you really enjoy the moment – and that’s one of the joyful things about a child.”
