Prince William, Kate Middleton and Prince Harry will reunite next week for another royal engagement.

On Thursday, the Duke and Duchess of Cambridge, along with Prince Harry, will attend the Grenfell Tower Memorial Service. Aside from the trio, Prince Charles and Camilla Parker-Bowles will also be in attendance, Hello! reported.

The service will take place at St. Paul's Cathedral. The royals have been very much involved in supporting the victims of the Grenfell Tower fire that occurred in June.

Seventy-one people were killed due to the incident while over 70 people were injured. The Duke of Cambridge and Queen Elizabeth visited the site and Middleton's husband described it as "one of the most terrible things I have ever seen."

In September, Prince William and Prince Harry visited the victims. According to Kensington Palace, the royal trio have individually sent donations for those affected by the fire.

"The tragedy at Grenfell Tower has left a number of local people in need of urgent assistance," the palace said in a statement. "The Duke and Duchess of Cambridge and Prince Harry are pleased the Evening Standard's Dispossessed Fund has immediately swung into action. As residents of the local area they are keen to offer their immediate support."

The royal trio was last seen together during the queen's platinum anniversary. Prince William, Middleton and Prince Harry arrived at the venue together in the same vehicle. There were rumors that the "Suits" star was already in London at that time, but she was not spotted during the celebration.

Following that event, the royal trio attended different secret meetings individually. Prince William met Jonathan Rea, a superbike champion. During the meetup, the Duke of Cambridge revealed that he loves motorcycles, but he puts that interest "on the back-burner" due to his growing family.

Meanwhile, Middleton met with psychiatric experts. On the other hand, Prince Harry graced the Walking with the Wounded reception in London on his own.

On November 27, Prince Harry and Markle have officially announced their engagement. Prince William and Middleton released a statement for the couple.

"The Duke and Duchess of Cambridge said of the engagement: 'We are very excited for Harry and Meghan. It has been wonderful getting to know Meghan and to see how happy she and Harry are together,'" the palace announced on Twitter.
