The couple announced earlier this week that they are expecting their first child together.

Meghan turned heads in a flowing blue dress with matching cape while Prince Harry was fitted out in a dark suit with his medals.
Meghan couldn't toast with wine like the other guests, but Prince Harry didn't let her suffer alone.
"Meghan and Harry both toasting with water at tonight’s reception (FIJIWater, natch)"
Fans of the royal couple took to Twitter to share their thoughts about Prince Harry's kind gesture, with one user saying it was "so sweet of him."
Users Waleska and Hannar R. said he is a supportive husband, while Qaqamba added: "So romantic. I love him even more now."
Josephine said it was "lovely [water emoji] for the mum to be" while Royal Dreams simply tweeted the hashtag "couple goals."
Meghan's dress for the evening was designed by SAFiAA, and to pay tribute to their hosts, she chose "Fijian Blue" material.
Eagle-eyed fans of the Royal family noted that the young couple's trip to Fiji shares parallels with the Queen and Prince Phillip's trip to the island back in the early fifties.
As a nod to the Queen, Meghan also wore pearl and diamond drop earrings which were gifted to her by the ruling monarch.
She completed her outfit by wearing a bracelet Prince Charles had given her on her wedding day back in May.
At the end of the evening, the couple posed with the Prime minister and his wife. Meghan posed with one hand gently cradling her baby bump.
