King Charles didn't love Princess Diana before marriage, Earl Spencer claims

King Charles did not love Princess Diana before their marriage.

Diana's brother, Earl Spencer, made this shocking claim in his new memoir, Swan Song: Diana, My Sister.

As per Earl, Charles was cruel to Princess Diana in the earliest days of their relationship.

"What makes these memories particularly painful is how early they occurred. This wasn't years into a marriage that had already collapsed – Charles is alleged to have been making comments that deeply hurt Diana before they had even reached the altar, a source familiar with Diana's story told RadarOnline.

The confidant further said, "Diana was incredibly young and suddenly facing the expectations that came with marrying the heir to the throne. Being criticized about her appearance and then hearing that the man she was about to marry wasn't actually in love with her would have been devastating."

"Charles Spencer's account presents a marriage where some of the fundamental problems were there virtually from the beginning," the insider continued.

 "Whatever happened subsequently, that is an extraordinarily sad foundation on which to begin married life," a tipster added.

For those unversed, King Charles tied the knot with the late Princess Diana in 1981.
