On the subject of her big day, Jessica said she hadn’t had time to even think about the ceremony.
‘I haven’t, not quite yet,’ she advised.
‘It’s definitely not something I’m thinking about at the moment.’
The surprise engagement comes after Jess recently opened up about their wedding plans - or lack of them!
Speaking on KIIS FM's Kyle and Jackie O show in August, the former Australian Idol star revealed that any thoughts of a wedding have never crossed her mind.
‘Have you organised any weddings? This boyfriend has been hanging around for a long time now,’ shock jock Kyle Sandilands asked.
‘I haven't had any time to pull that stuff together!’ Jess coyly replied.
Kyle crudely shot back: 'That's bull s**t, Jessica, I don't believe it.’
Congratulations to the happy couple! Some lovely times ahead!
