The royal rift between Prince William and Prince Harry seemingly rages on. The brothers are scheduled to appear at an event honoring their late mother, Princess Diana, but the two will not overlap. 

The Prince of Wales will attend the Legacy Awards held at the Science Museum in London on Thursday night, when he will present recipients with The Diana Award, established in his mother's honor two years after her death in 1997.

According to a press release by Kensington Palace, Prince William will meet with the winners that span from all over the globe, including Australia, Bangladesh, the Cayman Islands, India, Indonesia, Jamaica, Nigeria, Oman, Pakistan, Romania, the UAE, the United Kingdom and United States.

Prince Harry, who now lives in California with his wife Meghan Markle and their two children, will appear virtually to chat with the honorees, according to People magazine. His appearance will reportedly occur after Prince William has gone, further amplifying rumors that the brothers' relationship is still significantly strained. 

"There’s one huge obstacle in Harry’s way, and that’s Prince William," Kinsey Schofield, host of the "To Di For Daily" podcast previously told Fox News Digital of the brother's rift. "Harry will not be allowed to return in any capacity [to royal duties] if Prince William has any influence over the situation. William understands that Harry and Meghan don’t properly consider the consequences and aren’t trustworthy."
