Celebrity couple Hamish Blake and his wife Zoe Foster Blake have welcomed a son in time for Mother’s Day.

Sonny Blake was born on Saturday, with his parents taking to Twitter to announce his arrival.

“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.),” Foster Blake tweeted.

Blake, who won fame with his radio and television specials with Andy Lee, said “there was not a happier man on earth” following the birth of Sonny.

“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 said on his Instagram account.

“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).”
