Sophie looked slender and chic in a denim jumpsuit, teamed with a low-cut scarlet top (you can see the incredible outfit by checking out the video above).
She wore her long blonde hair in a loose up-do and accessorised with a simple silver bracelet.
Joshua meanwhile opted for a simple black t-shirt, jeans and black boots.
The pair appeared smitten over lunch and seemed locked in a loved-up conversation.
And it seems Sophie is certainly hoping for some exciting news some time soon.
She told HIT 105’s Stav, Abby and Matt recently that she’d like to marry her man.
‘I said we're going to get married, but he hasn't proposed so I probably should have thought that through and given him a choice in the situation,' she told the show.
‘But I'm hoping this year he proposes.'
