The first-time parents were more than happy to share the exciting news with their fans. Hamish posted a picture of Sonny on Instagram with the caption: "I met a young man called Sonny yesterday who I am particularly fond of. I just told him that @zotheysay is the best mum in the world, and as fate would have it, she's also his mum. He nodded, closed his eyes and said 'so that makes you my father'. I was very proud of his vocab for a 20 hour old. Today's a Mother's Day I don't think I'll forget in a hurry. There's not a happier man on earth. It's pure love (even if he wasn't in a novelty beanie)."
Similarly, Foster Blake introduced her newborn on social media: "Introducing Dracula Von Sandwich Twinklestar! Or as we call him, Sonny. Born yesterday, loved immensely, adored forevermore. (As IF I wasn't making the Mother's Day cut-off.)," she posted.
The beauty editor and columnist married the Gold Logie winner and star of Hamish and Andy's Gap Year in 2012.
