It looks like turning 30 really has made Prince Harry a grown-up.
The royal, who turned 30 on Monday, decided to cancel the birthday bash that had been planned in his honour because of his sister-in-law Catherine (née Kate Middleton) continuing illness with extreme morning sickness, reports Hello! Canada.
The party, which was to consist of just close family and friends, was rumoured to be organized by Kate, as well as her sister Pippa's party planning company, according to the Independent. An insider tells the publication Harry felt it was wrong to throw the party while the Duchess of Cambridge wasn't feeling well.
Prince Harry did celebrate the end of his successful Invictus Games, saying he would share a beer with David Henson, the captain of the British team, who happens to also turn 30 on Sept. 15, writes the Telegraph.
