Harry, the fifth in line to the British throne, was seen slipping into Markle's home Wednesday night. Harry, 32, shielded his face with a baseball cap and arrived under the cover of darkness with a duffel bag slung over his shoulder.
Markle, 35, and Harry have been spending time at Harry's cottage at Kensington Palace but Markle had to return to Toronto recently to fulfill her acting commitments on the television show "Suits."
Markle joined Harry shortly after the wedding at his Nottingham cottage before she returned to Canada at the end of the March.
Markle announced last week that she was shutting down her lifestyle blog, The Tig. Speculation has mounted that the move may be a sign that an engagement for Harry and Markle could be in the cards soon.
Markle, who has been extremely active on social media, would need to scale back her presence online if she were going to join the intensely private royal family.
In a farewell message to her Tig followers, Markle wrote, "You’ve made my days brighter and filled this experience with so much joy. Keep finding those Tig moments of discovery, keep laughing and taking risks, and keep being ‘the change you wish to see in the world.’ Above all, don’t ever forget your worth – as I’ve told you time and time again: you, my sweet friend, you are enough."
While insiders say that Markle intends to focus on her humanitarian work and her acting commitments, the closing of The Tig has still raised eyebrows that an engagement may be imminent.
Harry's current trip to Toronto will be a quick one. He's due back in London for a series of engagements tied to the Heads Together charity he started with William and Kate last year.
