Meghan Markle [VIDEO] is scheduled to marry Prince Harry on May 19, 2018, at St. George's Chapel at Windsor Castle. Many people are happy for Meghan who is going to be a Royal. However, some members of her biological family aren't thrilled about it.

Meghan's half-brother Thomas Markle Jr. reportedly wrote a letter to Prince Harry asking him to cancel the wedding [VIDEO]. He said it is a mistake for him to marry his half-sister because that will make a joke of the royal family heritage.

The hand-written letter

The hand-written letter was published by In Touch Weekly on Wednesday, May 2. The estranged half-brother describes the upcoming wedding as the biggest mistake in royal wedding history.

He calls Meghan several negative names and blames her for abandoning their father and causing him to go bankrupt after he helped her get started in her acting career.

The 51-year-old estranged brother said if it wasn't for their father, Meghan would be busing tables and babysitting to pay off her debts. He went so far as to call Meghan a below C average actress who appeared on every season of the legal drama, "Suits." He said becoming a royal has gone to her head, and he finds it strange that she has invited complete strangers to the wedding and not her own family.

Contradictions

This is contradictory to what Thomas Jr. once said about his half-sister. Earlier during Meghan and Harry's relationship, the half-brother complimented Meghan and he said he was proud of her.

Now, he has contradicted those remarks with something very cruel.

Thomas Jr. claimed that their father wasn't invited to the wedding even though some reports say not only was their father invited to the wedding, but that he will walk his daughter down the aisle. However, that role has not been confirmed.

Meghan's family

Thomas Jr. and Meghan haven't seen each other since 2011 when they attended their grandmother's funeral. He is joining other relatives who have spoken out about their discontentment because they have not been invited to the wedding. Meghan's half-sister Samantha Markle called Meghan a social climber and wrote a book about her entitled "The Diary of Princess Pushy's Sister."

Thomas sounds extremely bitter in his letter even though it has not been revealed which of Meghan's relatives have been invited to the wedding. He advised Prince Harry to cancel the upcoming fake fairytale wedding before it's too late.

Would he have called it fake if he had been invited? Do you think he has gone too far by advising the prince to call off the wedding, and by criticizing Meghan the way he did?
