Meghan's On Short Leash!

- 

JUST four weeks after her spectacular wedding to Prince Harry, new bride Meghan joined Queen Elizabeth for a solo overnight official engagement — and got a royal spanking!

While the two-day, 165-mile trip on Her Majesty’s private train was publicly touted as a major coup for the American-born beauty, GLOBE can reveal exclusively it was actually a hastily arranged crisis meeting to force the newly minted Duchess of Sussex to get with the royal program — or get gone!

“Meghan’s thrown royal rules out the window since she and Harry became engaged — and Her Majesty is not pleased,” a palace insider tells GLOBE.
