Kate Middleton and Prince William will reportedly try for a second baby this summer.

According to Vanity Fair magazine's royal correspondent Katie Nicholl, palace insiders claim the Duke and Duchess of Cambridge will have their second child soon.

"As for speculation about when Prince George will have a sibling, Nicholl reports that there are rumors among the couple's friends that they plan to try this summer," the report read.

The royal couple want Prince George to have a "normal" life.

"They take George to playdates at the homes of friends, among them Kate's old Marlborough friend Alice St. John Webster, who has a baby several months older than George," the magazine reported.

The world's gossip magazines have printed a stream of pregnancy rumours in recent weeks, with OK! Magazine reported that Kate was pregnant with twin girls.

Meanwhile InTouch Weekly claimed that the 32-year-old is already two months along with a baby boy.

However, in March, while attending the annual St Patrick's Day parade in Aldershot, Prince William revealed Prince George will not be getting a little brother or sister anytime soon.

Regimental Sergeant Major Ray Collister asked William if he is planning on having more children, to which the royal reportedly replied "maybe one day. One's enough at the moment."
