Unsurprisingly, she wasn't invited to the Royal wedding. She was in a wheelchair being pushed by her partner in front of the Palace gate.
Meghan Markle's half-sister reportedly clashed with security as she turned up at Kensington Palace to see the royal.
Samantha, 53, flew into the United Kingdom with the aim of confronting her half-sister but pictures appear to show her being met with a wall of silence after an embarrassing stand-off with palace security.
As reports the edition Express, 53-year-old Samantha tried to get into Kensington Palace, which is now home to her younger sister.
Meghan Markle has been a royal pro since her marriage to Prince Harry, but that doesn't mean it's been easy.
Harry and Meghan both share a love for traveling, and many have speculated that the couple will return from their lavish vacation with the big news of a pregnancy.
The acrimony stems from the ongoing beef over Meghan's father Thomas not attending the Royal wedding and a number of her half-siblings being left off the guest list - including Samantha.
Some of her comments seem a bit freaky though and it's hard to figure out what exactly is going on especially after she apologised to Meghan during an appearance on The Jeremy Vine Show last week.
"I think we would be hurt but it's their prerogative and they would know that from a distance we're congratulating them and wishing them well". "I can't give the details of that but I really wanted the world and really my sister and the British Royal family to know what happened and know the truth about a lot of things".
