Revealing the happy news on Twitter, Ian gushed that both himself and Craig are both "totally and utterly in love" with their sons.
Sharing a snapshot of two wristbands, one for each of the newborns, H revealed he's now a dad to two boys, who were born in the early hours on 6 March 2016 only three minutes apart.
The new arrivals are identified as 'Baby A' and 'Baby B' on the hospital bands, and the singer hasn't yet shared what names were chosen.
Ian and Craig first announced their very exciting news news back in December with an adorable animated video that shared the following message from the pair:
"Together we've been on lots of adventures. But our biggest adventure is about to begin. For a long time, we've been wishing, and our wish is about to come true.
"We are going to be dads!! There's more...it's Twins!"
