"The Duff" star later took to the micro-blogging platform to thank everyone for their outpouring love and support.

"Aww thank you for all the accepting tweets from everyone. I love you guys," she wrote, along with the hashtag "#pride."

The 18-year-old actress raised questions about her sexuality after she shared photos of herself kissing another female on Snapchat earlier this week. Moreover, a video of Thorne kissing the woman also surfaced online, fueling speculation that they were dating, according to Hollywood Life.

Thorne and Sulkin announced last week that they were going their separate ways after dating each other for a year and a half. The former couple even purchased a house together in February.

"After much thought and soul-searching, we have made the difficult decision to end our relationship," they said in a joint statement, according to Entertainment Tonight. "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."

Bella's new ladylove has been identified as her brother's ex-girlfriend Bella Pendergast. The pair has been thick as thieves ever since Pendergast dated Thorne's older brother Remy and the two have always expressed their affection for each other on social media with Thorne referring to her brother's ex as "girlfriend" on several occasions, but now their close friendship seems to have turned into a romantic relationship.
