Prince Harry Talks About The New Royal Baby: 'I Can't Wait To See My Brother Suffer More'

There is nothing like brotherly love, especially when it comes in the form of some good, old-fashioned ribbing.

The world learned that Prince Harry will be an uncle for a second time after Prince William and wife Kate Middleton announced they are expecting their second child. Their son, Prince George, was born last July.

"It's very exciting news," Harry told Yahoo at the launch of the Invictus Games in London on Monday. "I can't wait to see my brother suffer more and, with any luck, if it's a girl then he'll suffer even greater, I think. I'd love to see him try and cope with that."

While little George might look like he could be quite the rascal, Harry thinks the 1-year-old will be "over the moon" to have a sibling. He is, however, concerned about Middleton, who is suffering from severe morning sickness, otherwise known as Hyperemesis Gravidarum.

"In all seriousness, I hope my sister-in-law gets better soon and that the two of them have the opportunity to go through the whole process again with a little bit of peace and quiet," he said. "Last time I saw her she was feeling pretty poorly, but I think that's to be expected. Luckily, I'm not a woman, so I don't have to go through that."

The Duchess of Cambridge was forced to cancel public appearances due to her condition, the Daily Mail noted. She is currently being cared for at Kensington Palace.

Harry is thrilled for his brother, even though William's growing family reduces his chances of becoming king. The new royal baby will be fourth in line to the throne, while Prince Harry will move to fifth in line, according to the Telegraph.
