Prince Harry is set to dine at the 100 Women in Finance event at the Victoria and Albert Museum in London today (11.10.17).
The 33-year-old royal - who is dating 'Suits' actress Meghan Markle - will attend the annual event, which is designed to raise money for WellChild, and Prince Harry will even be making a speech.
100 Women in Finance counts Prince Harry and Catherine, Duchess of Cambridge among the non-profit organisation's list of patrons, and the flame-haired royal made an appearance at the same event in 2016.
Since then, a considerable amount of attention has focused on the Prince's romance with Meghan and earlier this month, a source claimed that the high-profile duo are "as good as engaged".
Prince Harry is reportedly waiting until the right moment to make a formal announcement of the couple's plan to marry each other.
A source explained: "While Meghan may not be wearing a ring or a formal engagement announced, it's fair to say they're as good as engaged now.
"They've spoken about their marriage plans openly with each other, and friends and family around them are pretty much thinking about wedding attire already!"
What's more, body language expert Dr. Lillian Glass previously revealed Prince Harry is more "relaxed" with Meghan than he was with his previous girlfriends, such as Chelsy Davy and Cressida Bonas.
She said: "First of all, we've never seen Harry this relaxed with anybody. That's number one.
"Every girl he's been with, there's kind of been a distancing, an uptightness about him, a real formality. But with Meghan you really see there's a connection."
