The happy couple told fans via Twitter this morning (23 July) that they have been busy working on a "secret project".
Former Miss Australia Erin tweeted: "So @example and I have been working on a secret project lately and thought it was about time we told you all!"
In an accompanying photo, 32-year-old Erin, who is wearing a neon orange bikini, cradles her baby bump as she stands by a balcony.
This will be the first child for the loved-up couple, who tied the knot in an intimate ceremony in Australia on 18 May 2013.
Chart-topping singer and rapper Example - real name Elliot Gleave - added his own unique twist to the wedding by playing theme music from Star Wars and Jurassic Park.
The 'Won't Go Quietly' hitmaker began dating Erin in 2011 after she interviewed him for MTV Australia.
The pair became engaged in November 2012 before tying the knot six months later - and now they have a new arrival on the way!
