After infamously pulling out of his daughter's wedding at the last minute due to an alleged health scare, a source has claimed that Thomas Markle Sr.'s heart attack and surgery were all a sham.

A source close to the Duchess of Sussex says that Markle Sr., 73, was never ill and faked an emergency operation as an excuse to not attend the royal wedding and garner sympathy.

But that has not stopped Samantha from continuously criticizing her sister on the platform.

'Glad you have so much time to gallivant around paying tribute to others while ignoring your own father!' she wrote.

'How cold can you be and look in the mirror? Harry? I guess I was right.'

Just one week before the wedding, The Mail on Sunday exclusively revealed that Markle Sr. had secretly collaborated with a British paparazzi photographer to set up 'candid' photos of himself preparing for the big day.

Days later, the father of three, who was set to walk Meghan down the aisle, abruptly pulled out of wedding, citing poor health.

Markle Sr. originally told TMZ that he was skipping the ceremony because he was 'too embarrassed' after it was revealed that he had staged a series of pictures that were later sold to newspapers around the world. He was then spotted grabbing two Happy Meals from McDonald's and a chocolate milkshake and then getting dinner at KFC, two days after allegedly undergoing heart surgery.

While Markle Sr. has become distant from Meghan, he recently reunited with his estranged son Thomas Jr. for the first time since 2011, as revealed by Dailymail.com.

A source described the meeting as having gone better than expected', but will take time for a 'solid reconciliation'.

Samantha, a mother-of-three who is writing a book about 'living in the shadows of the Duchess', took a short break from tweeting, before returning and appearing to respond to an interview her father did on Tuesday morning.

Thomas Markle told TMZ he's unfazed by reports that the Duke and Duchess of Sussex are fed up with him doing paid interviews with the media, and he wouldn't stop speaking out about his daughter and the Royal Family - no matter how 'frustrated' they get.

'I was silent for a full year and the press beat me up every day saying I was a hermit hiding in Mexico, so I gave my story,' he told TMZ.
