In March, they snuck away to Jamaica for Harry's friend's nuptials.
We'll say this: if not, it won't be for lack of wishful thinking.
If the couple do attend the wedding together it is said to mark a significant step in their relationship, as they have tried to keep their romance out of the spotlight since they first started dating in 2016.
Both Meghan and Harry have been crisscrossing the Atlantic in order to see each other since they began dating in July, with the Prince spotted arriving in Toronto on Wednesday to spend the Easter weekend with his girlfriend.
Due to the bride's strict "no ring, no bring" policy—which means guests can only bring spouses as a plus one to the ceremony—Markle will not be present at the church proceedings on May 20 in Berkshire.
There, she'll be in the company of Prince William, Duchess Kate Middleton, Prince George and Princess Charlotte, among other guests.
Markle's inclusion in Pippa's wedding to James Matthews is another sign of how serious the actress' relationship with Prince Harry is getting.
This will mark the couple's second wedding together this year.
The sister of the Duchess of Cambridge also announced that the ceremony will be taking place at St.
Mark's Church in Englefield, a Grade I-listed country church that dates back to the 13th century.
Prince William, Duke of Cambridge, and brother Prince Harry arrive for the wedding ceremony of Pippa Middleton at St. Harry's girlfriend, Suits actress Meghan Markle, did not attend the wedding, but was rumoured to be invited to the reception.
