She seems normal to me - I think slightly better speaking and presentation skills might of helped though. She obviously has some difficulty articulating her (mysterious?) family ancestry. And giggles has its limit. Also, I would not want her to be proud - definitely not a requirement to prove loyalty to her country of birth. Think of athletets who live and work in a different country while respresenting their country of birth during the Olympics and international main events - no different here.

To make it more approachable (to those who seem to misunderstand her statements) she could have said:

- If she has permanently moved to the UK: "My family heritage is nepali and I was born there - but now I live and work as a model in the UK." 

- If she is in the UK temporarily: "I work in the UK as a model but my home is nepal."

Beauty AND brains do cross path now and then - wonder how close she is.
