Gwen Stefani and Gavin Rossdale are planning on giving their unborn baby an unusual name - so the tot will fit in with big brother Kingston.

Stefani - who is currently pregnant with the couple’s second child - gave birth to Kingston James in 2006, naming him after the capital city of Jamaica.

And the parents are having difficulties thinking of a suitable name for the new baby.

Rossdale insists they would prefer something more traditional, but both feel they should opt for a more unusual moniker to fit with their eldest offspring.

He says, "There are some names floating around the house. We don’t want anything too crazy, but compared to a name like Kingston, there’s so much pressure on the poor guy or poor girl.

"Kingston set a pretty intense standard."
