Reports say that Duchess of Cambridge plans conception and Prince William's 30th birthday.

Just like a normal couple, the Duke and Duchess of Cambridge are also eager to have a child. However, conceiving an heir is not that easy. An insider in the royal palace confirmed that the two are trying. Another source said the couple hopes to conceive their first born between the last leg of their royal tour in September 2012 and summer 2013.

The source of Us Weekly also said that the couple aims to announce the pregnancy on New Year's Day or after Kate's first trimester. He also revealed that the pregnancy plan is the main reason why Prince William has not announced yet his long term career plans with the Royal Air Force because if the two are expecting, they will be full time in London.

Queen Elizabeth has been pressuring the couple to have an heir after being married for over a year. Prince William is 29 and Kate is 30 years old. The source further explained that The Queen instructed Kate to make starting a family a priority. However, she also told the prince not to let her royal duties and responsibilities to get in the way of happiness and his family.

During the Diamond Jubilee celebrations, Kate Middleton was spotted by onlookers and paparazzi with an alleged "baby bump" while shopping in West London.

There are reports that the Duchess is planning a surprise yet private celebration of Prince William's 30th birthday.

There was a leak that the Duchess will hold a party in one of the palaces as privacy is her main concern. She also collaborated with William's best pal Guy Pelly to make arrangements for the royal birthday bash.

Since it is not practical to go partying in London due to privacy and security issues, it is rumored that Kate Middleton and Guy Pelly plans to recreate one of the Prince's favorite clubs inside the palace. Whisky Mist, Boujis and Mahik are the top candidates for Prince Will's soiree.
