J.B. Gill won't allow his baby to date his JLS bandmates' children.
The 27-year-old singer - who is expecting his first child with his wife Chloe Tangney - admits he isn't keen on his offspring dating former colleague Marvin Humes' 14-month-old daughter Alaia-Mai or Oritse Williams' impending bundle of joy because the 'Beat Again' group are ''like family''.
Speaking exclusively to BANG Showbiz at the European premiere of 'Guardians of the Galaxy' in London's Leicester Square last night (24.07.14), he said: ''I'm sure we'll have play dates at some point.
''I don't know about [dating], it's like family! I don't know if cousins should be going out with each other.''
J.B. has confirmed Chloe is ''due soon'' but the couple have opted not to find out the sex of their baby and have decorated their nursery with neutral-coloured accessories and wallpaper.
He explained: ''We don't know the gender yet. I think girl, Chloe thinks boy, and it's probably about 70/30 [per cent] in favour of boy from our friends and family.
''We've kept everything neutral. To be honest, I'm not a huge fan of the pink or the blue. Even if I knew we were having a boy, I'd like it to be quite neutral. I don't having blue stuff but I'd rather not be so strict.''
The singer's former bandmate Marvin, who is married to The Saturdays star Rochelle Humes, has helped him prepare for fatherhood by gifting him a book on pregnancy.
J.B. added: ''He's actually given me a book called 'Pregnancy for Men', which is a really good book. It documents everything, it goes through it for men as men don't physically experience birth, so it's difficult to grasp what goes into it.''
