Britain's Queen Elizabeth is concerned that online dating sites are compromising security measures at Buckingham Palace.
Staff at the royal residence are using sites like Tinder to find would-be partners.
However, it's thought that with so many of the staff at the palace using such apps, security risks being breached, the Daily Mail reports.
Well-placed sources say that a number of the Queen's 800-plus staff use such online dating tools.
The source said: "There are real and serious security concerns at Buckingham Palace about members of staff use of dating apps such as Tinder, which can be rather sleazy.
"The palace police are particularly unhappy about the number of guests of servants staying overnight, especially when they may have only just met on Tinder.
"They know nothing of the guests' background and say they could be anyone.
"It is a security nightmare, especially in the current climate. The guests are allowed to stay at St James's Palace but some have complained that when they leave they get asked 'a million questions' by officers. But police say they are only doing their job."
A Buckingham Palace spokesman declined to comment on the issue, insisting they never discuss security matters in the media.
