Popular former Block couple Dale and Sophie Vine are expecting their first baby.
Landscaper and larrikin Dale, 32, posted a photo of Sophie's 20-week sonogram on his Instagram account to announce the news.
"Sophie_vine and I have kept a secret for 20 weeks now, and when we asked our 'baby to be' if it was cool to tell everyone at the 20 week scan, he/she gave us the big thumbs up," the dad-to-be wrote alongside the image.
Sophie later shared a shot of Dale reading the Dr Seuss classic I Wish That I Had Duck Feet to her precious baby bump.
The Geelong-based couple became fan favourites when they pocketed $355,000 on Nine's renovation series in 2012.
Dale returned for this year's Fans vs Faves series with fellow 2012 contestant and pal Brad Cranfield.
The pair walked away with $507,000.
