The news comes not long after his bandmate revealed that he was to become a dad too. JB Gill and his new wife Chloe were thrilled to be expecting when they shared their joy on the micro-blogging website on May 31.

Speaking about why they chose a church ceremony, JB told the magazine: "Chloe and I are both traditional in our views and our values. For me, marriage is the union of a man and a woman before God, so it meant a lot to us to have a proper church service with hymns."
The pair dated for six years after meeting on the X Factor - where JLS first found fame - and officially moved in together after their ceremony, having lived apart prior to the wedding.
