Who is Penny Wong's bride to be Sophie Allouache?
Sophie Allouache has been Penny Wong's partner for almost 18 years after the couple met in 2006.
She is a public servant who works as a manager for South Australia's Health & Department of Human Services and has expertise in early childhood health and mental health issues including eating disorders.
Ms Allouache is seven years younger than Senator Wong and is a former University of Adelaide Students' Association president.
In December 2011, Ms Allouache gave birth to the couple's first child Alexandra who was conceived through IVF and using a donor's sperm.
After the birth of Alexandra, Senator Wong and Ms Allouache said they would tell her who the father is.
Ms Allouache gave birth to the couple's second daughter Hannah in 2015, reportedly using sperm from the same previous donor.

She condemned the toxic debate surrounding the 2017 plebiscite on whether Australia should allow same-sex unions - held under Liberal prime minister Malcolm Turnbull - as an 'expensive stunt'.
However, when Australians voted overwhelmingly to approve such marriages she wept with joy.
'I hope that everyone in this parliament has heard the resounding voice of the Australian people today, a mandate for change, a mandate for equality,' she said.
'Because it is time.
'Thank you for standing up for fairness, thank you for standing up for equality. Thank you for standing up for our families.'
Seven years earlier, Senator Wong had controversially stuck to what was then Labor's policy maintaining that marriage was an institution between a man and a woman.
'On the issue of marriage I think the reality is there is a cultural, religious, historical view around that which we have to respect,' she said.
Senator Wong publicly came out as gay in 2002, shortly after she was elected to the Senate although her sexuality was not a secret to friends and family.
Ms Allouache, who works as public servant in Adelaide and is seven years younger than the Senator Wong, carried and gave birth to the couple's daughters Alexandra and Hannah after undergoing IVF and using the same male donor's sperm.
Senator Wong declared the birth of Alexandra in 2011 as a life-changing experience.

'Sophie and I are delighted beyond words. Like all new parents know, there's nothing like this,' she said at the time
Hannah, was born in 2015.
In a 2016 interview with Mamamia Senator Wong described her family life as 'boringly normal'.
'We have a station wagon and a mortgage and we live in the suburbs,' she said.
Senator Wong's office has been contacted for comment.
