For the moment, this is only a potential hot couple. They are not dating but Bella has expressed her opinion about Kristen. She considers The Twilight Saga’s actress to be super hot. And since her bisexuality was revealed in 2016, and confirming that at this moment she is completely single and ready for dating women, the chances of seeing both as couple are higher.
Of course, it can happen if Stewart pays attention to Bella’s declarations and feels the same way. For now, Thorne needs to practice her skills flirting with women, as she already admitted that she doesn´t know how to approach girls and is afraid to confuse friendship with sexual tension.
