Meghan Markle's estranged father Thomas is apparently gearing up to release his own menswear collection, according to a private tweet posted by his daughter Samantha.

Samantha, who is the Duchess of Sussex's half-sister, posted the tweet on Wednesday morning, reports the Daily Mail.

It read: "So excited about my father's new #clothing line for men! Will keep you posted!"

The move comes after the infamous paparazzi shots of Mr Markle shopping for suits for his daughter's marriage to Prince Harry in May.

Now the 74-year-old retired television lighting director is allegedly designing his own.

Samantha claimed back in May that her father's "staged" paparazzi photos were on her say-so and insisted it was all for the benefit of the Royal Family.

The 53-year-old mother-of-three insisted the stunt was not to rake in cash before the wedding.

The pictures commissioned by the former model showed her father surfing the net for pictures of the royal couple and apparently being measured for a suit in his hometown in Mexico.

Samantha's tweet concerning her father's upcoming clothing line has been brushed off as yet another publicity stunt by users.

One user called Trish said: "Meghan's father launching clothes line. Scam is his clothes going to have a label that says '100% made from money I made belittling my daughter in the media!' Wash with care made of 100% green vile that came from Sam's mouth."
