The Fast and the Furious actress shared her view after tweeting an article about South African runner Caster Semenya.

Caster, who is the favourite to win the women's 800m race at the Olympics, has become the subject on a gender debate due to the athlete being born without ovaries and with internal testes.

Semenya's testosterone levels are also three times that of an average woman due to a condition called hyperandrogenism.

Michelle tweeted a link to an article questioning whether Caster should be allowed to compete as a woman.

The 38-year-old added: "Runner wins gold as a woman? A transsexual category needed, hormones change physical capacity unfair."

While Michelle said no more on the issue, the tweet attracted backlash in her mentions.

One person wrote: "Trans women are women. Stop", while many others noted that Caster is not transgender, she was born intersex.

This comment comes after it emerged that Michelle will be playing a transgender assassin in a new film.

The action film, insensitively called (Re)Assignment, features Michelle as a male hitman who is "tricked" into getting a sex change by a rogue doctor, resulting in the newly female assassin going on a revenge rampage.

Transgender activist Elizabeth Marie Rivera hit out at the film, saying: "Why is being a transgender woman depicted as a cruel punishment?"

She also asked why a cisgender actress was playing a trans character.
