She's been keen to keep her life as normal as possible since she began dating Prince Harry 18 months ago.
But now the word on the street is that Cressida Bonas is worrying the team Royal security bosses because she won't stop using public transport. Well she is dating a prince after all!
The former dance student, known to her mates as 'Cressy', has been using London's buses and the Tube because she's keen to 'keep it real', but her bf's security guards are concerned she might be seen as a terror target.
A pal told the Daily Star Sunday: "Her own words are that she is 'keeping it real'. She still takes the Tube whenever she has to travel, despite Harry having a fleet of cars at his disposal.
"Last weekend she was out and about on the District and Circle lines. She feels lucky that her face isn't so well known, so she hasn't had to abandon her normal life."
Apparently Cressida has a number to call if things ever got scary.
Fancy a sneak peek at more snaps of Prince Harry?! Well you go lovelies...
