Speculation grew among Thorne's fans about whether the star was bisexual after a photo surfaced of the 18-year-old kissing another girl this month.
The actress responded to a fan on Twitter who asked "are you bisexual?" with a simple "Yes."
Thorne, who broke out on Disney Channel's "Shake It Up" and has appeared on MTV's "Scream: The TV Series" and the 2015 movie "The DUFF", was filled with gratitude after fans responded to the news with nothing but love and support.
"Aww thank you for all the accepting tweets from everyone. I love you guys #pride," said Thorne.
At the time, the former couple released a joint statement saying, "After much thought and soul-searching, we have made the difficult decision to end our relationship. We will always love each other and have a deep respect for one another, as we have each grown to be better people because of our time together.
"Our schedules made seeing each other difficult, and we decided that for now this would be best.
