It sounds like Prince George had a very good birthday.

According to his father, Prince William, the young royal -- who turned 3 on July 22 -- cleaned up in the gifts department this week.

William made the revelation while he and his wife, Duchess Kate, were attending the America's Cup World Series of yacht racing event in Portsmouth, England, on July 24.

When a 10-year-old boy who'd won a competition to design the race's trophy asked William what presents George received on his big day, William replied, "I am not telling. He got too many things -- he's far too spoilt," reports MailOnline.

William also explained, "He's not into boats yet."

But the Duke and Duchess of Cambridge certainly are.

Although Kate wore her favorite wedge heels for photos -- along with a very tight pair of skinny jeans that showed off her slim figire -- she donned a pair of black and teal sneakers when she and her husband of five years boarded a high-speed catamaran to cheer on Sir Ben Ainslie's Land Rover BAR team.

To mark Prince's George's third birthday, Kensington Palace released four new photos of adorable Prince George that show him playing with his dog, standing and sitting on a swing, and walking in the garden.
