Melania Trump and Donald Trump have been married since 2005. But an author has claimed that the couple doesn’t sleep on the same bed. In fact, the two reportedly don’t even sleep on the same floor.

In the book “Free, Melania: The Unauthorized Biography,” author Kate Bennett revealed that the president of the United States sleeps in the master bedroom on the second level of the White House residence.

The FLOTUS, on the other hand, sleeps on the third floor. More specifically, the mom of one sleeps in the room that was formerly occupied by Michelle Obama’s mother, Marian Robinson.

According to CNN, the First Lady has her own quarters in the White House, and she prefers to stay in her large, private suite of rooms on a different floor from her husband’s office.

The Trumps aren’t the only prominent figures who do not sleep in the same bed. It has been revealed that Prince Philip and Queen Elizabeth used to also sleep on separate beds while they were both staying at Buckingham Palace.

Royal expert Sally Bedell Smith told Daily Mail that the set up had nothing to do with Prince Philip and the Queen’s bond. Rather, they came up with it due to practical reasons. Smith said that it is a tradition among the British upper class to sleep on separate beds.

Prince Philip’s cousin, Lady Pamela Hicks, told Smith that the British upper class does not want to be bothered by their partner’s snoring so they opt to sleep on separate beds.

“Then when you are feeling cozy you share your room sometimes. “It is lovely to be able to choose,” she said.

Meanwhile, FLOTUS’s health crisis and her feud with Ivanka Trump are also included in Bennett’s unauthorized book about the First Lady. “Free, Melania” is now available at various bookstores in the United States. A summary is also available on Amazon.
