Princess Eugenie's mom Sarah Ferguson gets birthday wish from Prince Andrew

Sarah Ferguson’s 59th birthday on Monday included a royal touch — a birthday message from her ex-husband Prince Andrew, Duke of York.

“Happy birthday to @SarahTheDuchess,” a message sent from Prince Andrew's official Twitter account said. “Wishing you a very happy day!”

The well-wishes, however, may not have been sent personally by Prince Andrew himself. As the account’s bio notes, “The Official Twitter Account for The Duke of York. Tweets sent by HRH are signed - AY.”
