“It was a long ago and far away… Over a summer I was living in London,” she dishes, emphasizing her literary work is fiction, and not an exact reflection of their experience.

The reality star says the last time she saw the Harry Potter actor was when they met up in a bookstore after she discovered he was in town. She left a copy of a note novelist Sam Beckett had once written to a friend with his hotel—and he got the reference and knew where to meet for their rendezvous.

“That note and subsequent meeting at the bookstore was loosely detailed toward the end of the book,” the shares. “I’m afraid that is all I will say. Wink.”
