Marvin Humes wants his and Rochelle's baby to be called London.

The JLS pop star - who married The Saturdays beauty last summer - has said he wants to choose a ''crazy'' name for the couple's first child, and crooner Michael Buble gave his support.

Speaking on British TV show Daybreak - which will be aired on Monday (15.04.13), Marvin said: ''I wanted to go for some crazy names like London.''

His idea was granted with approval from Michael - another father-to-be with his wife Luisana Lopilato - who admitted he likes the trend of celebrity babies getting place names.

He added: ''I think London is a cool name. I like city names.''

Marvin reached out to his wife, who is reportedly a big fan of the 'Haven't Met You Yet' singer, after the stamp of approval.

The 'Proud' hitmaker said: ''Rochelle, if you're listening, Mr. Buble says London is a cool name!''

Whatever the baby's name, its mother recently admitted it will probably inherit the parents' tall genes.

She revealed: ''The poor thing will be quite lanky I think - we're the tallies!''
