Meghan Markle and Prince Harry 'privately congratulated' William and Kate Middleton on their anniversary, avoiding a public message

• Prince Harry and Meghan Markle privately congratulated William and Kate on their 10th anniversary.
• The couple's relationship with the Duke and Duchess of Cambridge has been strained in recent months.
• Harry saw William and Middleton for the first time since his Oprah interview at Philip's funeral.

Prince Harry and Meghan Markle "privately congratulated" Prince William and Kate Middleton on celebrating their 10th wedding anniversary on Thursday, Insider has confirmed.

The couple did release a public statement about William and Kate's anniversary, and the private congratulations were first reported by The Daily Beast. No further information about the anniversary message is currently known.

The news follows Harry and Markle's bombshell interview with Oprah Winfrey, during which the couple claimed members of the royal family made racist comments about Archie's skin and Markle said Middleton made her cry during the week of her wedding.

The relationship between the Sussexes and William and Middleton has been strained for years, even before their step back from the royal family at the beginning of 2020.

Prince Harry has spoken publicly about his rift with Prince William, saying he and his brother were "on different paths" in the fall of 2019.

It appears the couple's interview with Oprah did not help matters. Harry told Gayle King that he had conversations with William and Prince Charles that were "not productive" following the interview.

However, things seemed to change when Harry was unexpectedly reunited with his family for Prince Philip's funeral. Markle was unable to attend the funeral because her doctor did not give her clearance to travel while pregnant.

Although he did not process into the event next to his brother, Harry was seen chatting with William and Middleton after their grandfather's service, indicating a potential easing of the tension in their relationship.

The Duke and Duchess of Cambridge celebrated their wedding anniversary on Thursday with portraits taken at Kensington Palace earlier this week.

William and Middleton, who met while attending the University of St. Andrews in Scotland, were married in Westminster Abbey in 2011. They now have three children together.

Harry and Markle are set to come face-to-face with William and Middleton again over the summer for a statue dedication for Princess Diana in July.
