Prince Harry Drops Meghan Markle Off at the Airport

Prince Harry and Meghan Markle just hit another major relationship milestone — an airport send-off!

The royal dropped his leading lady off at London’s Heathrow airport on Sunday after spending a romantic week together. Harry was surrounded by a group of officers while Markle walked with an airline staff member to her gate.

Dressed in a long black wool coat, ripped jeans and her signature beanie, the Suits star was all smiles as she made her way through the terminal. The duo’s sweet send-off capped a festive week that included shopping for their first Christmas tree together and a date night in London’s West End to see The Curious Incident of the Dog in the Night-Time at the Gielgud Theatre.

The play marked the couple’s first public outing since their relationship was confirmed in October.

Markle’s week-long trip to London came about a week after Harry made a major detour following his two-week tour of the Caribbean to see her in Canada.

Despite keeping a low profile, Harry and Markle have expressed their romance subtly with personalized jewelry and matching accessories, and a source recently told PEOPLE that Harry is “very serious about her.”

On Monday, Harry was back to royal business, joining Prince William and Princess Kate to celebrate one of their favorite causes with a festive charity party.
