"It was a tough decision, but Demi and Max have decided to go their separate ways to focus on their respective careers," source told People magazine on Sept. 24. "They have respect and love for one another and will always cherish the time they spent together."

Earlier in the day Page Six reported that the relationship was on the rocks.

"It's not over yet," a source said, "but it's on its way there."

The split comes amid reports that Max has been flirting on social media with other pop stars. Earlier this month, screenshots seemed to show "The Young and the Restless" star calling Ariana Grande "my wife." He also allegedly told Selena Gomez, Demi's former friend, to "MARRY ME NOW" during an Instagram Live video. He also supposedly appeared in Miley Cyrus' comments.

At the time, Demi dismissed the screenshots as doctored.

"It's really sad when people FAKE images to put women against each other," she wrote on Instagram. "If women have conflict that's between them NOT YOU."

In addition to the alleged comments, fans noticed that Demi's sister and bodyguard both unfollowed Max on social media, which many saw as a sign of trouble.

Max hadn't appeared on Demi's Instagram since late August. She last appeared on his Instagram on Aug. 31. At the time, he called Demi "the hottest person on the planet."

Demi and Max got engaged on July 22.

In a touching post at the time, she said she fell in love with Max from the moment she met him.

"It was something I can't describe to anyone who hasn't experienced it firsthand but luckily you did too.. I've never felt so unconditionally loved by someone in my life (other than my parents) flaws and all," she wrote alongside images of the beachside proposal. "You never pressure me to be anything other than myself. And you make me want to be the best version of myself."

She continued, "I'm honored to accept your hand in marriage. I love you more than a caption could express but I'm ecstatic to start a family and life with you. I love you forever my baby. My partner. Here's to our future!!!"
