Thorne and Puth were first spotted holding hands while on a Miami beach stroll in December 2016. Their next public appearance was at Y100's Jingle Ball later that month, where Thorne watched him perform.
Things quickly got shaken up, however, when the "Lightswitch" singer accused Thorne of cheating on her ex-flame Tyler Posey. "I don't know Tyler personally, but I know he shouldn't be treated this way," Puth cryptically tweeted on 22 Dec. 2016. Thorne promptly cleared things up, however, tweeting that she had not publicly confirmed her split with the "Teen Wolf" actor. "Ty and I have been broken up for like over two weeks and charlie and I ARENT DATING we are friends," Thorne said in response to the backlash on Dec. 22, 2016.
Later, in a July 2017 SiriusXM interview, the former Disney Channel star stated that the drama could have easily been avoided if Puth had contacted her directly. "Charlie saw an old news article, and he didn't look at the date, and the date is old, and it's about me and Ty," Thorne said in an interview on SiriusXM's "The Jenny McCarthy Show." "I felt super bad."
