Pippa Middleton and Nick Jackson are allegedly expecting a baby after they were noted to be buying a massive house that comes with a room for a nanny.

The sister of the Royal Princess, Pippa Middleton, and stockholder Nick Jackson were seen buying a £3 million ($5 million) Victorian house in West London.

"Both Pippa and Nico were taken with it, and when they saw the plans couldn't wait to see the finished property," an insider told The Mirror, "They just have a feeling it'll be their first home."

The purchase of the mansion that includes six large rooms, a mini theater, plus nanny quarters, is the reason for all the stories that either Middleton is already expecting, or they are planning on trying for a baby soon.

"The separate living accommodation for childcare is particularly appealing for them which could signal they think starting a family isn't too far off," the insider said.

However, the gossip about the two settling down in the near future may not be true after all. On the contrary, their relationship may soon be a long distance one, since the 35-year old banker is set to leave for a new job in Switzerland.

Jackson, who used to work at Deutsche Bank, is about take a position in a multi-billion investment firm in Geneva.

Jackson and the 30-year old Middleton have been dating for 20 months now, and are still happy as ever, "They are very much an item, their relationship is very strong and they are happy together," a report mentioned.
