Prince William has been talking babies during his tour of Singapore.
The British royal revealed he wants to have two children with his wife, Kate.
He has spoken often in the past about wanting to start a family but had not given specific numbers.
The Duke and Duchess of Cambridge are on a nine-day tour of the Far East and South Pacific in celebration of Queen Elizabeth II's Diamond Jubilee.
"Someone asked him how many children he would like to have, and he said he was thinking about having two," student Corine Ackermann said.
They also visited a Rolls Royce jet engine factory in Singapore, touring the complex and unveiling the first engine produced by the plant, which opened earlier this year.
It was their second day in Singapore, which is the first stop on their tour. They'll also visit the Solomon Islands and Tuvalu.
