Prince William is already bracing for a little bit of "drama" when his 9-month-old daughter, Princess Charlotte, gets older. The 33-year-old British royal was spotted attending a rugby game in Wales recently and opened up about fatherhood to a group of reporters.

The Duke of Cambridge said Princess Charlotte is "very easy" and "very sweet,” but jokingly added: “All the fathers say to me, 'Just you wait, when they get to 9 or 11 they get crazy.”

He went on, "I'm looking forward to it. There will be some drama."

Prince William, who was attending the RBS 6 Nations Wales vs. France game Friday, continued saying that things have been going "very well" since his wife, Kate Middleton, gave birth to their second child. The pair, who married in 2011, are also parents to 2-year-old Prince George.

"No broken bones so far," Prince William said, according to E! Online. "But they are trying, running around and pushing things and jumping."

Last month, he gushed on being a dad, telling comedy duo Declan Donnelly and Ant McPartlin for an ITV documentary that fatherhood made him more emotional.

“I’m a lot more emotional that I used to be,” he said. “I never used to really get too wound up or worried about things, but now the smallest little things can get — I can feel — you well up a little bit more.” 

According to the Telegraph, he also revealed during the interview that he sometimes fears he won’t be “around to see [his] children grow up.” Prince William’s mother, Princess Diana, died in 1997 when he was 15.
