Prince William, the Duke of Cambridge, confirmed last month that his wife, Duchess Kate Middleton, is not pregnant, but according to new claims, the royal couple is actively trying to add another baby to their young brood.

According to a print report from OK! Magazine, Middleton, 32, and Prince William, 31, are hoping to soon add another child to accompany their first, eight-month-old Prince George. “They’re all over each other in fully baby-making mode,” said one insider, another adding that the pair “can’t keep their hands off each other.”

The couple, currently in the midst of a three-week tour, landing in New Zealand with their royal offspring on Monday, is rumored to be prepping for a second pregnancy in the coming months. “Kate said she hopes to have two more little ones around her this time next year,” said an insider, adding that the Duchess, previously rumored to be expecting twins in March, is hoping for her next pregnancy to result in two children. “She thinks it would be fun to have a boy and a girl,” said a source.

According to the tabloid, Prince Charles, 65, advised the young couple to keep at least 18 months in age between their first and second child, a gap between the “heir and the spare.” Separate from the familial advice, the tabloid claims that the duchess held off on conceiving a second child due to avoid pain during the royal tour. “She doesn’t want a repeat,” said one source, referring to Middleton’s hospital stay in December 2012 while pregnant with George due to a bout of acute morning sickness.

Prince William confirmed to a solider at a military base St. Patrick’s Day celebration in March that Middleton is not pregnant, despite multiple reports in recent weeks that the duchess was with child. When prompted to confirm or deny the pregnancy rumors, he responded, saying, “One’s enough at the moment,” before teasing the addition of a second royal baby in their future, later adding, “Maybe one day.”

The Duke and Duchess of Cambridge kicked off their 19-day tour Monday, the first formal tour for HRH Prince George of Cambridge. The couple will spend just over one week in New Zealand before jetting off to Sydney, Australia, spending several days down under before returning to the UK.
