Marvin and Rochelle Humes could name their child after the city of London.
Singer Marvin, 28, said he wanted to give his first born a 'crazy name' in honour of the capital city and he hopes that Rochelle, 24, will agree.
In his bid to try and convince The Saturdays member that London is a good name, he enlisted the help of heart throb Michael Bublé during an interview on morning TV show Daybreak.
The Canadian crooner, who is also soon to be a dad, was in favour of the unusual choice and said it was a 'cool name'.
Marvin said: "I wanted to go for some crazy names like London."
Michael, who is expecting his first child with wife Luisana Lopilato said: "I think London is a cool name. I like city names."
Marvin added: "Rochelle, if you're listening, Mr Bublé says London is a cool name!"
Last week Rochelle was treated to a baby shower and hints were dropped that she could be expecting a little girl as her friends arrived with bunches of pale pink balloons.
