Britain's Prince Philip is recovering at King Edward VII Hospital in London after undergoing a hip replacement.
Both the queen, 91, and Philip have suffered some health issues in recent years.
Some media reports in the United Kingdom indicated that the timing of Prince Philip's hip replacement surgery was in preparation for the activities that will be involved in the royal wedding ceremony.
Prince Philip, the Duke of Edinburgh, is in "good spirits" after undergoing a hip replacement on Wednesday, Buckingham Palace has said.
Prince Philip has been a constant and often mischievous presence at royal functions for decades and is well-known for punctuating royal pomp with a taste for off-colour jokes.
Prince Philip was also forced to pull out of an event with the British Ministry of Defence at Windsor Castle in March.

Kensington Palace shared that Harry and Markle have invited 2,640 people into the grounds of Windsor Castle to watch the couple's arrival, as well as their departure as they depart the castle on a carriage procession through the town of Windsor.
It is carried out under a general anaesthetic or an epidural, with the surgeon making an incision into the hip, removing the damaged joint and replacing it with an artificial joint made of a metal alloy or ceramic.
Opened in 1899, the Marylebone institution is favoured among senior royals, with Philip, the Queen, Prince Charles and the Queen Mother among past patients.
He is "progressing satisfactorily at this early stage", the palace added.
When it was announced previous year that he would be retiring from official engagements, Buckingham Palace stressed that the decision was not health-related and he had the full support of the Queen.
The hospital was rated as "requires improvement" by inspectors a year ago. During Queen Elizabeth's Diamond Jubilee celebrations in June 2012, he was hospitalized for a bladder infection.
Philip is now expected to attend Harry and Markle's May 19 wedding at St. George's Chapel with other members of the royal family. It was said that the surgery would take place on Wednesday, April 4.
