Don't expect Gwen Stefani
and Gavin Rossdale to be stocking up on baby items in pink or blue just yet. The couple, who are expecting their second child
, will find out if they're getting a boy or a girl on delivery day, Rossdale said Wednesday.
"We don't know [the baby's gender]. It was a surprise last time so we're kind of working on that this time," he told Ryan Seacrest on his KIIS-FM radio show.
"There are some [names] floating around the house, bouncing around the walls."
But will the new baby's name measure up to his brother's? "Not too crazy," said Rossdale, 42, who added that compared to a name like Kingston, "there's so much pressure on the poor guy or poor girl. Kingston set a pretty intense standard!"
The big brother-to-be, who turns 2 next month, has also been entertaining his parents with his growing vocabulary. "He speaks now," said Rossdale. "It's pretty cute. He's got a funny way of saying things and a funny voice. He's pretty vocal."
Stefani, 38, has described her son as a "chilled-out little guy ... he's super-cute and super-entertaining."
