Suits star Meghan Markle has been romantically linked to Britain's Prince Harry, with the royal said to be "besotted" with the American actress.

Thirty-five-year-old Markle, who is best known for her role as Rachel Zane in the legal drama, met Prince Harry in Toronto last May when he was promoting the Invictus Games.

The pair are said to be taking their new relationship slowly, but a source told The Express that the 32-year-old royal is "besotted" with the star already.

Markle has reportedly visited him in London a few times since they began seeing each other, and was spotted in the royal box at Wimbledon.

"William and Kate really liked her and she fitted in straight away," the source said.

Markle married film producer Trevor Engleson in 2011 before splitting after three years. She was then linked to Rory McIlroy.

Prince Harry split from long-term girlfriend Cressida Bonas in 2014.
