An exciting report from the US today has revealed the sex of Prince William and Kate Middleton's third child.
Star magazine claims to have discovered from palace sources that the eight-months pregnant Kate is expecting a baby boy!
'They know the gender, but have only told the queen and a few family members,' a Kensington Palace insider told the publication.
Bookies have tipped that the royal couple are opting to give their third child a traditional name - including choices like Arthur and Albert.
'Prince George and his sister Charlotte are very excited to meet their new baby brother,' a source spills to Star. 'George especially couldn't stop clapping when William told them.'
The new royal bub will be fifth in line for the throne - following Prince Charles, Prince William, Prince George and Princess Charlotte.
The royal family has not responded to Star's report.
