The Queen is reportedly set to host a joint 40th birthday party for Prince William and Kate, Duchess of Cambridge this summer.
William turned 40 today, while Kate reached the milestone in January.
The two venues which are reportedly being considered for the event are Windsor Castle and Sandringham Estate.
Her Majesty could attend the party herself, but will wait until closer to the time to confirm her attendance, a palace source told the Mirror.
The Duke of Cambridge spent his 40th birthday visiting the Big Issue vendor who showed him the ropes when he went undercover as a seller.
William caught up with Dave Martin on his pitch at a Tesco supermarket in Hammersmith, west London, on Tuesday.
He took Mr Martin, 60, a slice of his birthday cake and chatted to him about how he was doing, during the private visit.
The men got to know one another when the duke carried out a stint as a Big Issue vendor earlier this month. It allows the homeless to earn an income by selling the magazine.
William is the cover star of the latest issue and wrote an article about his experience, describing his time with Mr Martin, a Big Issue seller for 11 years, as “eye-opening”.
The duke has set out his key birthday as a turning point, pledging more help for those who are struggling.
He vowed to continue raising the issue of homelessness, in his article, and pledged to introduce his children to charities supporting rough sleepers, just as his mother Diana, Princess of Wales, did with him.
“I have always believed in using my platform to help tell those stories and to bring attention and action to those who are struggling,” he said.
“I plan to do that now I’m turning 40, even more than I have in the past.
“So, for my part, I commit to continue doing what I can to shine a spotlight on this solvable issue not just today, but in the months and years to come.”
