The 32-year-old is said to be enjoying dates with actress Meghan Markle , who he met in Toronto in the summer while promoting his Invictus Games for disabled service men and women.
Harry, who has previously said he hates social media, also 'follows' Meghan via an Instagram account - and she follows him back.
According to the Daily Mail, Meghan is one of only a handful of people to be followed by Harry's secretive profile.
It will added further fuel to claims the pair are an item with one source saying Harry is “besotted”.
Divorcee Meghan, 35, who stars in legal drama Suits, is claimed to have made several low-key visits to London to see Harry, where she has not only met his friends but also Prince William and Kate.
A source said: “He’s happier than he’s been for many years. He’s in a very relaxed period of his life and Meghan has come along at the right time.”
Although she has kept quiet, Meghan posted a photo on Instagram in which she wears a blue bracelet almost identical to one of Harry’s .
The Toronto-based star shares several interests with the prince, including charitable work.
They also have mutual friends, including Violet Von Westenholz and Arthur Landon. So is she Prince’s new girlfriend?
