The actress portrayed the late Princess of Wales - who died in a car accident in Paris in 1997, aged 36 - in 2021 psychological drama film Spencer.
Kristen has now said whenever she thinks about Diana she becomes emotional and that she cannot drive around London or Paris without thoughts of the late Princess invading her mind.
Speaking about being 'haunted' by Diana, she told the Daily Telegraph: 'I still am. I can't drive round this city, and Paris for that matter, without thinking about her. All the love that poured out of this woman... I can cry about her at any moment.'
The American star thought Spencer director Pablo Larrain was 'insane' for casting her as the British royal, and he pleaded with the filmmaker to cast someone else - but he refused.
She added: 'I told Pablo he was insane and he should probably hire someone else, but he refused to accept that. There were some massive distinctions between her and me.
'It was the statuesque thing. It was the eye colour - I have green eyes; she has very famously blue eyes that match her ring. So I was like, 'Should we make the engagement ring green, then?
'[They] were pulling me under and Pablo was like, "You really must detach from those things - this is about spirit".'
But one of the reasons director Pablo, 49, persevered with Kristen as Diana was because he could see 'a little bit of overlap in terms of [their] experience'.
Like Diana, Kristen was 'so young and vulnerable' being photographed a lot when she rose to global stardom in the Twilight film franchise in the 2000s and 2010s.
Towards the end of filming Spencer, Kristen admitted she felt like 'a shell' which she believes is how Diana felt at the end of her marriage to then-Prince Charles.
The role earned Kristen her first Oscar nomination but she missed out on the gong to Jessica Chastain for her portrayal in The Eyes of Tammy Faye.
Spencer focuses on three days of the late royal's life in 1991.
