Prince Harry Seen With Meghan Markle For First Time

Prince Harry has been dating actress Meghan Markle since the summer ... but they've escaped the lenses of London ... until now.

The Sun snapped Harry for the first time Tuesday night with his new American TV star GF, where he reportedly snagged tickets to a play at the last minute.

We're not surprised Meghan got the royal treatment for their date night. Quite frankly, anything less would be ... rubbish.
