Prince William and Kate Middleton shared 2 new portraits to mark their 10th wedding anniversary

• Prince William and Kate Middleton celebrated ten years of marriage on Thursday.
• The royal couple released two new anniversary portraits ahead of the special day.
• Taken by a celebrity photographer, the photos showcase the duo in a less formal light than before.

Prince William and Kate Middleton released two new portraits on the eve of their 10th wedding anniversary on April 29.

The photos, which were posted on the couple's Twitter account on Wednesday evening, feature both William and Middleton dressed in blue and posing affectionately on the grounds of Kensington Palace.

Celebrity photographer Chris Floyd captured the intimate photos earlier this week, which showcase the royal couple in a less formal light than previous anniversary announcements.

In the first photo, the duo holds hands while William looks lovingly at his wife. The second photo shows the couple in a smiling embrace, with Kate's sapphire engagement ring on display.

Some on social media were quick to note the apparent similarities between the Duke and Duchess of Cambridge's laid-back manner with the approachable tenor of Prince Harry and Meghan Markle's engagement photos.

William and Middleton wed on April 29, 2011, at Westminster Abbey, while millions around the globe watched the ceremony and subsequent procession to the Buckingham Palace balcony, where the married couple appeared together for the first time.

The two met at St. Andrews University nearly 18 years ago and have since grown their family to five, with the births of Prince George, Princess Charlotte, and Prince Louis.
