Charlie Puth lashed out on Twitter, saying he is not interested in dating Bella Thorne any longer after she posted two pics with ex-boyfriend Tyler Posey, writing: “taking a trip down memory lane.”

Charlie wrote, “I can’t believe what I’m reading. No one should have their heart messed with like this, and I’m not going to be in the middle of it.” Also, “I don’t know Tyler personally, but I know he shouldn’t be treated this way.”

I messed a lot of things up, I get it if we can’t be friends….you know who you are.

One tweeter had suggested that Bella was dating Tyler when she and Charlie started dating, to which he responded, “She told me she was not with him anymore. This is all news to me.”

In a recent interview with Paper, Bella tweeted a link to the article, writing: “Ty and I have been broken up for like over two weeks and Charlie and I ARENT DATING we are friends. That article was written forever ago.”
