The 27-year-old actress is currently dating model Stella Maxwell, but Kristen remains open-minded when it comes to her love life and has admitted she could easily see herself falling for a man in the future.
She explained: "Some people know they like grilled cheese and they'll eat it every day for the rest of their lives.
"I want to try everything. If I have grilled cheese once I'm like, 'That was cool, what's next?'"
The Hollywood actress' most famous romance was with her former 'Twilight' co-star Robert Pattinson.
And although their relationship ended in acrimonious circumstances, Kristen has insisted her love for Robert, 31, was totally authentic.
Speaking to Harper's Bazaar magazine, she shared: "I've been deeply in love with everyone I've dated. Did you think I was faking it?"
Kristen has since admitted to being bisexual, and has insisted she's never felt confused by her own identity.
She said: "I've always embraced a duality. And really, truly, believed in it and never felt confused or struggling. I just didn't like getting made fun of."
Kristen was bullied at school when she dressed like a boy and she confessed the criticism from her classmates made her feel miserable.
The 'Personal Shopper' star explained: "Not all little girls are that way. And it really hurt my feelings, like badly. I remember being in the sixth grade [aged 11] and [people would say] 'Kristen looks like a man. You're a boy', or whatever, and I was so offended, horrified and embarrassed.
"Now I look back on it and I'm like, 'Girl, be proud of that!'"
Meanwhile, Kristen also admitted she dislikes having to explain her love life to other people.
She said: "There's this idea that you're beholden in some way, and I resent that.
"And it comes across like I'm ungrateful or something but, actually, I just find it weird to talk to the general public as a whole."
