They met in Los Angeles a few years ago, and then they reunited in Jamaica where they hooked up. Harry confirmed that he wrote the song "Carolina" about his one night stand with her. The song's name is "Carolina" because she was born in South Carolina. In the song, Harry even mentioned her name and the fact that she moved from Carolina to LA:
"She's got a family in Carolina / So far away, but she says I remind her of home / Feeling oh so far from home / She never saw herself as a west coaster / Moved all the way 'cause her grandma told her 'Townes, better swim before you drown'"
Townes knows the song is about her, since her father heard Harry singing it at the Today show and told her that Harry has written a song about her. Since then, Harry has said during interviews that he's still in touch with Townes and that they're friends.
