Prince William Spills Family Plans, Wants 2 Kids with Kate Middleton

Prince William divulged his plans for having a family with Kate Middleton during his trip to Singapore on Wednesday, furthering rumors that the Duchess of Cambridge is already pregnant.

The royal couple, both 30 years old, is touring the Far East in celebration of Queen Elizabeth II's Diamond Jubilee. The Duke and Duchess of Cambridge visited Singapore's Gardens in the Bay when William opened up about having children.

Corine Ackermann, 17, overheard the prince answering a fan's question about potential additions to the royal family.

"Someone asked him how many children he would like to have and he said he was thinking about having two," Ackermann, student at the Tanglin Trust School, told People magazine.

The media constantly speculates whether or not Kate is pregnant, and the Duchess recently added to the frenzy after opting for water instead of white wine on Tuesday.

One of the 1,000 fans that crowded the venue trying to get a glimpse of the couple asked the prince about his ideal superpower.

"That's a hard question, I'm not sure," replied William, according to the Daily Mail. "I'll have to think about it. I think invisibility."

Then, the same fan posed the question to Kate moments later.

"Kate said she had to be invisible if Prince William was, otherwise he would be able to sneak up on her," explained 13-year-old Charlotte Phillipson. "She found it really tricky to answer."

The Duchess of Cambridge changed from an Alexander McQueen broderie anglaise suit into a patterned silk shirt and dress by Asian designer Raoul before visiting the city's Rainbow Centre on Wednesday.

Along the nine-day tour, the Duke and Duchess will visit Malaysia, where Kate will make her first foreign speech at a hospice. Later, the couple will attend an official dinner at His Majesty the Yang di-Pertuan Agong's official residence. They will also visit the Solomon Islands later next week.

They young royals already visited Singapore's Botanical Gardens and dined with the nation's leaders.
