The Sunday Mirror reports that fellow band mate Rochelle Wiseman's boyfriend - who just happens to be Marvin Humes from JLS - is very keen to volunteer for childcare duties!
The singer told the paper that if Una and Ben ever fancy a night off from the baby, then he and Rochelle would happily take over!
"We'd love to babysit Una's baby and have already put in for those duties," he said, adding: "If we're home one night and Una and Ben want to go out on the town then of course we'll look after the little one. I think we'd make great babysitters. I love kids and babies!"
Bit more exciting than having granny round to change nappies and do the midnight feed, isn't it?
Who would be your dream celeb babysitter?
