While the prince was invited to the wedding of Princess Anne's only son Peter Phillips, Davy was not placed on the official guest list and the snub has upset the couple, The Mail on Sunday reported.
A source told the British newspaper the fact that Prince William's girlfriend, Kate Middleton, was invited to the May wedding was particularly insulting to Davy.
"The explanation being offered is that, at the time, Harry and Chelsy were going through a wobble. But Chelsy sees it as a direct snub and is pretty miffed at not having been invited, especially as Kate plans to
go," the unidentified source said.
The source told the Mail with Chelsy also not receiving an invite to the Royal Family's Easter skiing trip, the constant snubs seem personal.
"She was not invited to ski, which doesn't bother her because she'd rather go home to Cape Town, but she would like to have been invited to Peter's wedding. She's becoming the Royals' Cinderella," the source told the newspaper.
