ENTERTAINMENT NEWS - The star of US drama Suits told Vanity Fair the pair are enjoying "special" time together.
"We're two people who are really happy and in love," the 36-year-old said.
Markle revealed she and the prince had been in a relationship for six months before the rest of the world found out at the end of 2016.
There was a media frenzy when it was revealed Harry was dating the US star, the pair having met in July last year.
The intense interest prompted the prince to issue a statement, attacking the press for subjecting his girlfriend to a "wave of abuse and harassment".
'This is our time'
She admitted to Vanity Fair that the situation "has its challenges" and "comes in waves", and that "some days it can feel more challenging than others".
"Right out of the gate it was surprising the way things changed," said Markle, who plays lawyer Rachel Zane in the TV drama.
"But I still have this support system all around me, and, of course, my boyfriend's support."
