In that speech, Meghan addressed the challenges of funding an education, saying she relied on "scholarships and financial aid programs" to get through her degree.
But Meghan’s estranged sister Samantha – who has long been critical of the Duchess – took to Twitter to disagree.
“Dad paid her college tuition!” Samantha wrote, referring to their father Thomas.
“She [Meghan] forgot the most important part of her speech and there are receipts to prove it.
“I love my sister but this is ridiculous.
“You can’t lie like this, Meg! Delusionally absurd!”
It has previously been reported that Thomas Markle paid for Meghan’s tuition at a catholic school with winnings from a lottery ticket.
Thomas won the California State Lottery in 1990, and apparently walked away with $US750,000.
He had five numbers, which included Meghan’s birth date - August 4, 1981.
