Kate, the Princess of Wales, debuted a new, blonder hairstyle on a church outing Sunday with her family amid their summer vacation. Kate was photographed in the passenger seat of an SUV driven by her husband Prince William, with their three children -- Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7 -- in the backseat.

Catherine, the Princess of Wales, was spotted around Balmoral Castle in Scotland, on Aug. 25, marking a rare public appearance since she was diagnosed with cancer earlier this year.

Princess of Wales Kate Middleton, known for her signature brunette style, appeared in Scotland with hair several shades lighter — prompting debate over whether it’s a genuine shift or just the sunlight catching her highlights.
