What could possibly top living in the White House?
Michelle Obama knows.
Dropping by The Late Show, the 52-year-old happily spilled to host Stephen Colbert that one of her big "highlights" was a "sleepover" in the the Queen's home.
"There are so many oh my god moments, I mean sleepover at Buckingham palace," the American First Lady revealed, explaining she and the president had the privilege after attending a state dinner at the Queen's residence in 2011.
Of course the king of late night had to ask about their royal escapades.
"Did you and the Queen paint each other's toe nails?" He asked, with Michelle giving the 52-year-old her signature laugh.

Michelle may not be calling Her Majesty "Lilibet" just yet, but the mum-of-two did get to take full advantage of the Buckingham Palace room service.
"I do remember ordering some fries," she said. "I am a big french fry fanatic."
Giving praise to the palace's chefs, she complimented: "They were good. They have good fries at the palace."
How could you top that?

Over the years the Obamas, Michelle in particular, have become close friends with the royals.
The First Lady instantly hit it off when she met Harry to help promote his Invictus Games.
Earlier this year she spoke of the honour of working with his charity and thanked him for his service, “I want to, of course, start by thanking Prince Harry for his outstanding leadership and for bringing the Invictus Games here to Orlando."
"He is truly our Prince Charming.”
Later, she let slip one very adorable detail the ginger royal.
"I have to say the most precious thing, if you haven't already fallen in love with him, is to see him with his nephew," said Michelle of Harry, who sat red-faced right next to her.
Speaking of the evening in which she and her husband met Harry as well as the Duke and Duchess at their Kensington Palace residence, she quoted Prince George who asked the royal, “Uncle Harry, why are you so quiet? Why are you so quiet?”'
Harry then piped up, calling the moment "so embarrassing". He explains that George noticed that he was on his “best behaviour” as he is “normally throwing him around the room and stuff."
"And he didn't understand what is wrong with you," the first lady said to Harry. "He’s got a pretty good uncle over here."
Charming AND good with kids... Hello Harry!
