The actress has made her very first official appearance with Harry at the wheelchair tennis match at the Invictus Games - Paralympic competition was founded by Harry in 2014 for wounded service members.
The actress was seen leaving a Heidi Klein designer beachwear store, possibly hinting at a winter holiday in the sun.
Her arrival in the United Kingdom comes as speculation mounts over an imminent engagement between Meghan and Harry. The "Remember Me" star and the Royal Foundation patron opted to delay it so as not to steal the limelight from Queen Elizabeth and Prince Philip who just celebrated their 70th wedding anniversary on Monday.
The 36-year-old Markle recently finished out her contract with "Suits" when she concluded filming for the US network show's seventh season.
"It's been an absolute pleasure and honour being your 'STAND-IN" for the last 2 seasons, ' Nicky wrote. Wishing you all the happiness in the world Bella'. The public is just waiting for them to officially confirm it.
