With the media locked in a revolving door of will-he-won't-he surrounding Meghan and Samantha's father Thomas and his attendance at Saturday's royal wedding, the latter has been doing the rounds of TV talk shows to give rolling updates and explain her role in Markle's freaky decision to stage photographs with a paparazzi photographer.
But Morgan was having none of her explanations lashing out at Samantha for her "shabby" treatment of her sister.
The host then broke out a question that surprised his guest but asked what many observers had been thinking.
But today, Samantha accused the media of "twisting" and "skewing" anything she has said about her half-sister - who she has not spoken to since 2015 - in an interview with GMB. She took full responsibility for setting up her father Thomas' fake photo shoot.
"It was done with the good intention to make the royal family look good, and himself", she said.

Also on Tuesday, Department of Homeland Security unveiled a strategy to guide cybersecurity threats. Nielsen: "I have not had a conversation with Ambassador Bolton about that particular issue".
But Morgan was not accepting this because he believes that Markle is still stinging from her sister's rejection.
Clearly irked by the claims, Morgan responded: "There's no bigger media vulture in this wedding than you". But since he was outed by CCTV footage talking to photographers to allegedly stage the snaps, Samantha now claims "media vultures" have put too much pressure on her father.
"We don't respect it coming from a woman who's been trading off her very tenuous connection with Meghan Markle".
He continued: "You've spent the last two years criticizing her, you called her a narcissist, selfish, that Hollywood changed her and that Prince Harry shouldn't marry her, yet you have the gall to blame media vultures". "Doing a deal with the paparazzi knowing that they'd [Prince Harry and Meghan] be horrified".
Piers added, "It seems to me her father, your father, has let her down".
