Prince Harry to Host Coldplay at Kensington Palace

The concert will raise money for Harry's Sentebale charity.

Sentebale has been so successful that it's recently expanded its presence from LeSotho to Botswana.

Prince Harry returned to LeSotho last November to open the Mamohato Children's Center, which provides education, camps and psychological support to 1,500 HIV-positive children each year. At the center's opening, Harry named one of the rooms in the center after Princess Diana.

Princess Diana was one of the first to end the stigma surrounding HIV and AIDS and worked tirelessly to end discrimination and raise funds for education and research for those living with the disease. Prince Harry, who formed the charity in 2006, has vowed to carry on his mother's work.

HIV is the number one cause of death in 10 to 19-year-olds in Africa, according to Sentebale.

"I hope she's looking down, you know, with tears in her eyes, being incredibly proud of what we've established, I suppose," Harry said. "I'm sure she's longing for me to have kids so she can be a grandmother again."

He added, "I hope that everything we do privately and officially, that it makes her proud. I think losing your mother at such a young age does end up shaping your life massively. Of course, it does, and now I find myself trying to be there and give advice to other people who are in similar positions."

All proceeds from the Coldplay concert will go towards supporting children living with HIV and AIDS.
