Prince Harry and Prince William seemingly avoided each other at a family event as the feud between the two royal brothers carries on. 

Harry, 39, and William, 42, both attended a memorial service for their mother’s brother-in-law, Lord Robert Fellowes, on Thursday, according to the BBC.

The Duke of Sussex departed from his home in Montecito, California, to join his family, including the Prince of Wales, at St. Mary’s Church in Snettisham, England.

Fellowes’ memorial service was held close to the royal Sandringham Estate in Norfolk. 

According to the BBC, a source who attended the service confirmed that Harry and William were both present.

"It was wonderful that both princes were able to attend their uncle’s memorial service yesterday at St. Mary’s Church," a church warden, who requested to remain anonymous, shared with the BBC.

"The service was a lovely family occasion celebrating the life of such a special man. Many friends were also present and also many members of the St. Mary’s Church family."

Kensington Palace declined to comment on the matter after Fox News Digital reached out.

Lord Fellowes was married to the late Princess Diana’s sister, Lady Jane Spencer, for more than four decades. The couple had three children together and was an uncle to Harry and William.

Meanwhile, Prince Harry avoided yet another run-in with his estranged brother earlier this summer.

In June, the Prince of Wales attended the wedding of Hugh Grosvenor, the Duke of Westminster, and Olivia Henson at Chester Cathedral in northern England. While the Duke of Sussex was invited to attend, Harry regretfully declined in an effort to avoid an "awkward" encounter with William, a royal expert told Fox News Digital at the time.

"Even if Harry showed up and slunk into the back row, there would be enough press coverage and general hysteria over the two brothers being in the same room to overshadow the wedding entirely," Christopher Andersen, author of "The King," told Fox News Digital.
