See Photos of Meghan and the Queen at Their First Official Event Together

Last weekend, Meghan Markle celebrated Her Majesty's annual birthday celebration known as Trooping the Colour (opens in new tab) alongside Prince Harry and other immediate royal family members. Today, she's spending time with her grandmother-in-law (opens in new tab) in Chester, England, for her first royal event without her husband.

The Duchess of Sussex is wearing a Givenchy dress, the designer label that was behind her wedding gown (opens in new tab), and the Queen chose her go-to shade of lime green (opens in new tab). Unsurprisingly, Meghan chose a more formal dress that covers her shoulders since, you know, she's traveling solo with the Queen.

Meghan traveled 205 miles by royal train (opens in new tab) with the Queen to open the new Mersey Gateway Bridge and the Catalyst Science Discovery Centre (opens in new tab) museum. FYI, the Queen's personal train is typically reserved for more senior members of the family, so clearly Meghan already has the whole royal thing nailed down. Her sister-in-law, Kate Middleton, didn't make an appearance with the Queen until almost a year after her and Prince William's wedding. (opens in new tab)

As for Meghan and the Queen's itinerary, according to the Catalyst Science Discovery Centre website (opens in new tab), it's "the only museum in the U.K. which explores the science and technology behind the chemical industry and its impact on our lives." After the royals open the museum, they'll travel to Chester, England that's about a half hour away from Cheshire to open the Storyhouse Theater before having lunch at the Chester Town Hall.

Sounds like a fun day with granny!
