Speculations over a royal pregnancy for Prince William and his wife Catherine Duchess of Cambridge have intensified this week as the two royals make a tour of the South Pacific.

While in touring the Gardens by the Bay in Singapore, Prince William made a casual comment on the number of children he wanted to have.

According to the Daily Beast, Corine Ackermann, 17, was with classmates from the Tanglin Trust British School when she overheard the Prince's comment. "Someone asked [the Duke] how many children he would like to have, and he said he was thinking about having two," Ackermann told reporters.

While the comment would not normally incite any pregnancy rumors by themselves, they came a day after his wife Kate refused to toast with wine during a state dinner, instead taking up a wine glass filled with water.

The Daily Beast also reported that the Duchess declined wine twice in toast to the Queen, while husband William readily drank his glass of red Bordeaux. The same report stated that sources close to the royal couple confirmed the pregnancy but said that the couple wished to hold off the announcement for "as long as possible."

This is not the first instance the Duchess has been rumored to be pregnant.

During a trip to Denmark last year, Catherine's refusal to eat peanut butter sparked rumors that Catherine was expecting. Expecting mothers are advised to stay away from peanut products during pregnancy. Glamour Magazine UK also reported that speculations over a twin pregnancy were denied in September 2011.

The royal family in Great Britain has not yet given any confirmation of a royal pregnancy.
