And according to The Daily Telegraph, Cressy's decision to face photographers and pose for pictures at the recent WE Day UK event in London came as she tries to face her shyness.
Speaking about the former dance student, a friend told the paper: "When she is at a party she is terrific fun. She is very funny, incredibly affectionate, incredibly sweet.
"Harry won't find anyone better than her because there isn't anyone better than her.
"The thing about her that would surprise people is she is quite strict - strict with herself and strict with Harry, and it's no great coincidence that Harry is a changed man since he has been seeing her.
"She just will not put up with bad behaviour. She tells him off, she says 'you've not having another drink', he doesn't smoke anymore, she has stopped all that."More Prince Harry...
