Prince Harry’s Old Friends say he is ‘lost’ and reveals exclusive details of he is facing with Meghan Markle, as the prince turns 40 and remains estranged from family

Prince Harry is preparing to turn 40 on September 15 — but it is pretty safe to assume his brother, Prince William, the future King of England, won’t be wishing him a happy birthday.

The renegade royal will enter his fifth decade with an A-list party organized by his wife Meghan Markle, 42, Page Six is told.

But it will be in Montecito, California, 5,000 miles away from the father and brother he grew up with after the tragic death of his mother, Princess Diana, when he was just 12 years old.

This week, Harry was in the same room with William for the first time in over a year — but there was no thawing of the frost that set in after Harry’s infamous Oprah Winfrey interview and the publication of his memoir, “Spare.” It’s said the two brothers, once thick as thieves, did not speak, and William does not want Harry at his own eventual coronation.

Harry, who left the royal family for life in America in 2020, flew back to his homeland to attend a memorial for his uncle, Lord Robert Fellowes, a long-time royal courtier who was married to Princess Diana’s sister, Lady Jane Fellowes.
