The British pop rocker became a first-time father on 13 March (14) when his wife Giovanna gave birth to a baby boy named Buzz.
Now she reveals that she went into labour while enjoying a birthday dinner with Jones, who turned 28 on 12 March (14).
In her blog for Hellomagazine.com, she writes, "I still had two and a half weeks left until my due date and had all sorts of plans for my last bit of 'freedom', but it seems Buzz wanted to come out and join us - eager to say hello to the world. In fact, we were out for dinner with all the MCBusted family (celebrating Danny's birthday) when my waters broke - so I'm pretty certain Buzz just wanted to be part of the fun. I can't tell you how giddy we all were when we left our friends in the restaurant knowing that the next time we'd see them we'd have a child."
