There's more bad blood between members of Meghan Markle's family.

The actress-turned-royal bride's half-brother, Thomas Markle Jr., 50, has spoken out to reveal that he doesn't think his own sons should be asked to attend their aunt's wedding when she marries Prince Harry, 33, on May 19.

Tom Jr. -- who shares a father with Meghan, 36 -- told Britain's Sunday Mirror that his boys, Thomas, 26, and Tyler, 25, and their mother, his ex-wife Tracy Dooley, "should not be getting any invite to the wedding."

His comments come, reports the Sunday Mirror, after Tracy and their sons gave a TV interview in which they said they would be "honored" to attend Meghan and Harry's wedding.

"It's got to stop. The boys were babies when they met Meghan last and Tracy has never even met Meghan, ever," Tom Jr. told the newspaper.

He explained of Tracy, whom he divorced in 2000, "Tracy and me stopped living as man and wife three months into the marriage because the relationship was such a disaster. She never wanted the Markle name when we were married and now suddenly she acts like she's still part of the family."

"I don't want her to have anything to do with us and the boys shouldn't go along with it. They shouldn't be at the wedding either," he continued.

"Both boys were always Dooleys as kids. I got sick of making the name an issue with Tracy and ultimately she had her way. They're Dooleys. You cannot pick and choose when you're a Markle," he added.

"I don't believe Tracy or my sons have the right to call themselves Markles. If this embarrasses Meghan than I am sorry, but Tracy can't go on claiming to be a Markle," Tom Jr. said.

The irony of it all is that it seems unlikely that Tom Jr. himself -- who hasn't seen or talked to his half-sister in years -- will even score an invitation to the royal wedding, especially since he's repeatedly spoken to media outlets about his famous sister.

Tom Jr. (pictured) -- who's further embarrassed Meghan thanks to legal troubles including a January 2017 arrest on weapons-related charges following a domestic dispute with his girlfriend -- and older sister Samantha Grant, 51 -- who's writing a book about Meghan -- both lived in the same household as their newborn half-sister when they were teens. Their dad, Thomas Markle Sr., married Meghan's mom, Doria Ragland, in 1979. The former Hollywood lighting director, 72, and his social worker and yoga instructor wife, 61, split when Meghan was 6.

But both Tom Jr. and Samantha, who suffers from multiple sclerosis, have admitted they've fallen out of touch with their famous sibling. Meghan, who got engaged to Harry in November 2017, has not spoken publicly about family members' repeated media interviews nor given any hint as to whether or not they will be invited to celebrate with her and Harry on their big day.

Should Meghan decide to extend an olive branch, however, there should be plenty of room.

She and Harry will exchange vows at St. George's Chapel at Windsor Castle, which can hold about 900 guests.

It's been reported that some of the famous faces who will be at Meghan and Harry's wedding include her "Suits" co-stars, such as Patrick J. Adams and his wife, actress Troian Bellisario, as well as Meghan pals like tennis champ Serena Williams and actress Priyanka Chopra.

"The "Quantico" actress played coy recently when she was asked if she might also be serving as one of Meghan's bridesmaids. Former U.S. President Barack Obama and wife Michelle Obama are also believed to be on the invitation short list, as they're friends with Harry.
