Prince Philip is under the weather again.
The Duke of Edinburgh has withdrawn from official engagement after falling ill.
A Buckingham Palace spokesperson confirms to E! News the 91-year-old other Philip was scheduled to attend a gala reception for the Royal National Institute of Blind People at St. James's Palace, but missed the event because he's feeling "unwell."
No word exactly what ails him. But Prince Philip, who was hospitalized last June for a bladder infection, is expected to attend tomorrow's coronation service, celebrating 60 years of Queen Elizabeth II's reign.
Phlip's illness didn't stop Her Majesty from getting out, as the queen took in performances from London stage star Michael Ball and the operatic quartet Il Divo.
