Princess Diana's brother set to tie the knot

Princess Diana's brother, Charles Spencer, has announced that he is engaged to Canadian philanthropist Karen Gordon.

Spencer will be tying the knot at his ancestral home in Althorp, in central England, less than two months after his nephew Prince William marries Kate Middleton at Westminster Abbey on April 29, reports CBS News.

"Charles, the ninth Earl Spencer, is delighted to announce his engagement to Karen Gordon, a Canadian philanthropist who is the Founder and CEO of Whole Child International," said the official statement, obtained by People magazine Tuesday.

Spencer's representatives added that the marriage would take place during a private ceremony on June 18 but no further details would be disclosed.

Gordon is the founder and chief executive of Whole Child International, a Los Angeles-based charity that works to help orphaned, abandoned, or abused children.

It will be Spencer's third marriage. He has four children from his first marriage, to Victoria Lockwood, and two children from his second marriage, to Caroline Freud.
