Meghan Markle and Prince Harry are "frustrated" with the former "Suits" star's father, Thomas Markle.

Amid his latest interview with The Sun, a royal source tells ET the Duke and Duchess of Sussex "haven't had any contact" with him lately.

"[They] are frustrated he keeps speaking to the tabloids and taking payment for interviews," the source adds.

Thomas recently sat down with the outlet for his second-ever on-camera interview, in which he said he thinks his 36-year-old daughter is "terrified" of her new life as a royal.

"I see it in her eyes, I see it in her face and I see it in her smile," he explained. "I've seen her smile for years. I know her smile. I don't like the one I'm seeing now. This one isn't even a stage smile -- this is a pained smile."

"It really worries me," he continued. "I think she's under too much pressure. There's a high price to pay to be married to that family."

Later in the interview, Thomas also claimed he has been unable to reach Meghan by phone.

"Since the [first] interview [with Good Morning Britain], the phone number that I call doesn't work anymore," he said. "The, I guess, liaison with the royal family never answers back, and there's no address I can write to, so I have no way of contacting my daughter."

"My message [to her] would be, 'I love you, I miss you, I'm sorry for anything that went wrong,'" he added. "And I want to be her child's grandfather and I want to be near them. I want to be a part of their life. I'd like to put our differences behind us, and get together. I miss you very much."
