Matty also took to Instagram to share the sweet news.
"Still letting the last 24hrs sink in," he began. "They’ve been the most rewarding, loving and emotional I’ve ever experienced. @ladyandacat you did the most incredible job bringing our little girl Marlie-Mae Rose Johnson into the world. Becoming a Dad was better than I ever could have imagined."
Matty and Laura don't just have their new arrival to be excited for, on their recent 'Babymoon' the couple got engaged. “You are my favourite everything @matthewdavidjohnson. YES to a lifetime of love and flamboyant dance moves with you my honey,” Laura wrote alongside a selfie of the pair.
Meanwhile Matty wrote, “There’s absolutely no one else I’d rather grow old and senile with. I can’t wait to start a family together and now I can’t wait to be your husband!”
Congratulations to the new parents!
