Royal watchers were scrutinising the duchess of Cambridge on her New Zealand tour today, after husband Prince William appeared to hint a second baby is on the way. Kate, however, looked to dampen the speculation bydrinking wine and going on a jet boat ride, neither of which are recommended for pregnant women. The royals' eight-month-old son Prince George, third in line to the British throne, has been the star of their New Zealand tour so far. But William suggested during a walkabout in the North Island town of Cambridge there may soon be another royal baby to share the spotlight.
