Meghan spoke at the time of her struggle to finance her higher education and her "personal feeling of pride and excitement" when she studied for her degree.
And with rumours of a rift brewing between Meghan and Harry's brother and sister and law, Prince William and Kate Middleton, it could be shaping up to be a dramatic festive period.
Meghan's bump went viral as she and Harry stepped out on Tuesday evening.
Harry and William, who became close friends of Henry van Straubenzee while at Ludgrove School, have been patrons of the fund since 2009.
We may not seen Meghan until Christmas, when she and Harry are expected to join the Cambridges and the Queen at Sandringham for Christmas.
The Duke and Duchess of Cambridge found themselves in a snowball fight as they paid a heartfelt tribute to RAF families separated from loved ones over Christmas.
Rumblings of discontent between the young royals can be traced as far back as a bust up at Christmas a year ago where Kate reportedly attempted to explain the rules of the Monarchy to Meghan, a move which, according to The Sun, she didn't take very well.
The royal couple quietly entered the church through a back entrance shortly before 7pm, with Pippa Middleton, sister to the Duchess of Cambridge, and her husband James also in attendance.
According to Sunday Times royal correspondent Roya Nikkhah, both Harry and Markle were involved in the service, with Markle giving a reading of the poem "Our Deepest Fear" by Marianne Williamson and Harry sharing an appeal for the charity. "They don't really get on", a source told the Daily Mail.
In the official baby announcement, Kensington Palace merely stated that the royal baby would be making an appearance in the United Kingdom spring, which is our autumn 2019.
But a spokesman for Kensington Palace said: "This never happened".
The royal family will spend the holidays together.
