Can't believe its already been a year! Prince William and Catherine, the Duchess of Cambridge celebrated their first wedding anniversary on Sunday privately at home in Anglesey.

The royal couple celebrated another wedding this weekend as well. They attended a friend’s wedding. "They sat close to the front of the church, so they had to walk down the aisle together to get there," said a source for US Weekly. "It made a few people chuckle."

According to the magazine, friends congratulated William and Kate on their one-year anniversary, but the couple didn’t want to "take any attention away from the bride and groom."

They reportedly didn’t party too hard after the nuptials. They headed home for "a very special day at home" on Sunday.
