Sam has spoken to WHO before about her love for Dave, and how she credits him with helping her through some dark times.
“We’re in a really good place, we’re the best of mates, we laugh all the time,” Sam gushed to WHO last year.
The 30-year-old has been dating Dave for over a year and she’s admitted previously that they’re keen to move in with one another ‘one day’, yet when it comes to marriage she admits they’re taking it one step at a time.
"We don’t put pressure on the relationship, we just take one step at a time," Sam added.
That said, she does credit Dave for helping her deal with her anxiety and depression.
"He's the one to pick up the pieces after a breakdown or anxiety attack," she said previously.
The exciting gender reveal party was also attended by both Anna and Tim Robards, who fell in love on the first season of The Bachelor Australia.
And it was revealed at the party that Anna's sister is having a boy.
Anna and Tim - who said 'I do' last year in a lavish ceremony in Italy - have spoken about their family plans before, and they told Confidential that children have always been part of their life plan.
"A family has always been part of our life plan," Anna told the publication.
Anna added: "It will probably be towards the end of this year that we start trying."
