The 22-year-old actress - who recently reunited with her British actor boyfriend of four years following her "momentary indiscretion" with her 'Snow White and the Huntsman' director Rupert Sanders in August - believes fans treat their relationship like a movie and thinks it is better to keep people guessing.
Asked about her relationship with her 26-year-old 'Twilight Saga: Breaking Dawn Part 2' co-star, Kristen said: "Funny you mention that. I'm going to just let people watch whatever little movie they think our lives are."
She initially hesitated and appeared uncomfortable answering the personal question on the 'Today' show this morning (07.11.12) but then brushed off the situation by adding: "Keep 'em guessing, I always say."
The actress also appeared on the US morning show 'Kelly & Michael' today wearing a bright Victoria Beckham dress to promote the final instalment of the vampire franchise which is due to be released next Friday.
The shy actress recently admitted she thinks it is important to laugh at herself and believes you can't take everything too seriously.
She said: "Um, yeah, I mean, if you can't laugh at yourself, there's definitely a problem.
"Best not to even approach that aspect. Just think about actually who you are, rather than, you know [what's projected on you]."
