Meghan Markle's half-sister isn't sure if she'll be invited to her wedding to Prince Harry.

While the flame-haired prince is yet to pop the question, there is speculation aplenty that the pair will marry next year, and the 'Suits' star's sibling Samantha Grant hinted they may tie the knot at some point but wouldn't be offended if she wasn't asked to go to the ceremony.

Samantha - who hasn't spoken to Meghan in nine years - said: "I don't know if I would be hurt, and out of love and respect I would go; of course I would go.

"We'll see if I get an invite."

The 52 year old also insisted her half-sister - whose dad is Caucasian and mother is African-American - wouldn't feel any pressure becoming the first bi-racial princess or duchess in British royal history.

When asked if her sibling might be affected, Samantha told 'Good Morning Britain': "She is confident, not only in herself as a woman, but in her relationship with Harry and love that they have so that should speak for - and carry - them and everything else.

"And that being said, it seems a non-issue."

Last year, Samantha compared Meghan to Harry's late mother Princess Diana - who died in a car crash aged 36 in August 1997 - and former US Secretary of State Condoleezza Rice, insisting she is a "peaceful person" who isn't much of a "partier".

Samantha - who shares the same father, Thomas Markle, as the star, and is writing a book about the actress called 'The Diary of Princess Pushy's Sister' - said: "She's got the eloquence of Condoleezza Rice, and the grace of Princess Diana.

"She's not wild, she's not garish, she's not a partier.

"She's just very beautiful and conservative, very real, very giving. She's just a peaceful person."
