  • The Duke and Duchess of Sussex's new portrait was taken at their Montecito, California home
  • Prince Harry and Markle will host an episode of TIME100 Talks on Oct. 20

Meghan Markle and Prince Harry have posed for a new official portrait in their mansion in Montecito, California.

In the stunning black-and-white portrait, which was shared on Twitter by royal correspondent Omid Scobie, Markle looks effortlessly chic in a plain white T-shirt that she paired with a sleek black blazer and matching trousers. Prince Harry also rocked a suit for the portrait, pairing it with a button-down oxford but ditching a tie.

Prince Harry and Markle's new portrait was captured by Los Angeles-based photographer Matt Sayles. His works usually "reflect a more inclusive image of beauty" and highlight stories from underrepresented communities, according to his website

The release of the Sussexes' portrait comes amid the announcement that the couple will host a special episode of TIME100 Talks titled "Engineering a Better World" on Oct. 20.

"The Duke and Duchess of Sussex, both TIME100 alumni, are among the most influential voices in the world," Dan Macsai, Time executive editor and editorial director of the TIME100 about the royal couple, said in a statement. "We look forward to working with them to elevate essential voices and highlight real solutions to some of the most pressing issues of our time."

The discussion, which focuses on the pursuit of a "more compassionate, safe, and trustworthy digital world," will feature appearances from Reddit co-founder Alexis Ohanian, Rappler CEO and executive editor Maria Ressa and Center for Humane Technology president and co-founder Tristan Harris, per the press release.

Activist and founder of The Loveland Foundation Rachel Cargle, author and co-director of the UCLA Center for Critical Internet Inquiry Safiya U, and the hosts of the podcast "Teenager Therapy" will also be included in the episode.

Harper's Bazaar reported, citing an unnamed source "close" to Prince Harry and Markle, that the Sussexes had personally overseen the preparations for the upcoming virtual conversation, including choosing the theme, the guests who will appear in the episode and the topics to be discussed.

In related news, reports have surfaced that Prince Harry and Markle may return to the U.K. before the year ends, with plans to spend Christmas with the royal family.

However, an unnamed insider recently told Entertainment Tonight that Prince Harry has no plans to go back to England for now, though he could still have a change of heart in the coming months.
