Kate Middleton cheered on her home team during the America's Cup World Series sailing regatta in Portsmouth, England, looking lovely as usual, even while markedly more casual than we're used to seeing her.
Middleton, who is formally known by her royal title as Catherine the Duchess of Cambridge, attended the adrenaline-pumping sailing races on Sunday wearing a sporty casual outfit in the British team's navy, gray and red colors.
The 34-year-old Duchess has a vested interest in sailing as a patron of the 1851 Trust, a foundation to inspire the next generation of English sailors. She's even joined the national team for a training session on the high seas before!
Middleton's husband, Prince William, the Duke of Cambridge, was also in attendance. He met with young fans, including one who wanted to know what their eldest child, Prince George, received for his third birthday on Friday. "I am not telling, he got too many things," William said, according to the AP. "He's far too spoiled."
