Prince William thinks his son got too many presents on his third birthday.

William declined Sunday to say what gifts Prince George received when he turned 3 two days ago.

"I am not telling, he got too many things, he's far too spoiled," William said.

He was asked during a visit to see Britain's America's Cup ships at the crew's home base in Portsmouth before observing the competition.

He was joined by his wife, Kate, on the visit.

The couple released new photos of George to mark his birthday. The pictures distributed Friday show George, who is third in line to the throne, playing on a swing and sitting with the family pet, a dog named Lupo.

The four photos were taken earlier this month at the family's country home.

A palace statement said William and Kate hope people will enjoy the new photographs taken by Matt Porteous.

George is behind his grandfather, Prince Charles, and his father William in the line of succession.
