It was the butt that launched Facebook fan pages, but a royal expert says Pippa Middleton was wearing a fake bum to give it just the right look during the royal wedding three years ago.
Middleton, the sister of Catherine, Duchess of Cambridge, "had a false bottom" under her dress, French royal watcher Stephane Bern claimed on his France 2 TV show, the Daily Mail reports.
"I repeat it: She had a false bottom. You take her away from that and she has normal buttocks," he said. "It was an optical illusion. She knew there were a billion people watching. It was the moment to show it."
He didn't say how he knows Middleton used a fake butt.
