Max Ehrich has accused Demi Lovato of "exploiting" their breakup

Writing in the comments section of her photos, where she was showing off her new hair, he wrote: "Exploiting our breakup for clout at PCA is not chill. Stop talking about me on award shows. Thanks."

Meanwhile, Max had recently confessed he feels he's been part of a big "calculated PR stunt" following his split from Demi, 28, after she released her own song about their break up.

Slamming his former fiancé, he said: "It's just the craziest thing. This is the most bizarre experience that I hope no one ever has to experience, ever. Because no person deserves to feel this way. Pete Davidson didn’t deserve to feel this way. Do you think he wrote that text to Mac Miller? Ha. Open your eyes. Calculated PR stunt, but my team is going to hate me for saying any of this."

Max insisted he was "in love" with Demi, and now feels like he was "used" by her.

He added: "I was in love. The whole world should f****** know it. I thought I found the real deal, now I found out that I was used. But I hope the song is number one, because you know what, if that's what someone wants in the material world, here you go, you have it. I hope this makes you happy. Enjoy. You just lost someone who loved you fully, completely, infinitely, for everything."
