Prince William: Prince George 'Is a Little Bit of a Rascal' [VIDEO]

Prince William has said that his newborn son George is a "little rascal", according to excerpts from an upcoming interview.

On Monday, CNN released a teaser of their upcoming interview with the future King of England. He said that his almost one month old son reminded him of his 28-year-old brother, Prince Harry. He drew comparisons between the two.

"He's a little bit of a rascal, I'll put it that way, so he either reminds me of my brother [Prince Harry] or me when I was younger, I'm not sure," Prince William said.

Prince William further commented that overall, his son with the Duchess of Cambridge Kate Middleton were doing well and that Prince George also liked to get his diaper changed. The monarch also mentioned how the family dog Lupo has been coping with the new addition.

"Catherine is very well, [and the dog] Lupo is coping ... He's been slobbering around the house a lot, so he's happy," he said.

Prince William also discussed the whirlwind of attention that accompanied the July birth of his son. He admitted that he and Kate Middleton were overwhelmed but happy to show off their son outside of St. Mary's Hospital in London.

"It's not somewhere I enjoy being, I know that the position I'm in that's what's required of me to do. ... It's nice that people want to see George, so, you know - I'm just glad he wasn't screaming his head off the whole way through," he said.

Prince William's Passion: New Father, New Hope, is scheduled to air on CNN and CNN International on Sunday, Sept. 15, at 10 p.m. ET.
