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.

Proof the extended royal family is in fact at Balmoral Castle: Prince William, Kate Middleton and the entire Wales fam (Prince George, Princess Charlotte and Prince Louis) were all photographed attending church at Crathie Kirk in Aberdeenshire,

Kate tends to keep a low profile. The last time we saw her was at Wimbledon in mid-July, when she was still rocking her signature brunette with just a hint of caramel. Fast-forward a few weeks, and she's several shades lighter, showing off a sun-kissed blond that feels perfectly timed for late summer.
