In new pictures, obtained by The Sun, the couple is seen casually dressed, walking across the airport tarmac after exiting the plane. Markle, who turned 36 on August 4, is all smiles, wearing blue jeans, a tank top, grey baseball hat, sandals, dark sunglasses and holding a burgundy fedora, a backpack and what appears to be a gift wrapped in bubble wrap.
Meanwhile, Prince Harry is dressed in blue slacks, a white-and-blue checkered button-up, grey baseball cap, tan shoes and dark sunglasses. In the snaps he's seen putting his arm around his lady and giving a thumbs-up to other passengers.
The couple was escorted by Harry's royal protection cop and an airport worker.
According to the publication, Markle flew to London from her home in Toronto, Canada, after finishing her work on Suits and reunited with the Prince following his return from Sicily. The two will now spend time celebrating Markle's birthday and taking in the gorgeous scenery.
