The 28-year-old singer and her former fiance have called off their relationship after two months of their engagement, according to a source close to Lovato who spoke Thursday on condition of anonymity due to the sensitivity of the matter.
"It was a tough decision, but Demi and Max have decided to go their separate ways to focus on their respective careers," the source said.
"They have respect and love for one another and will always cherish the time they spent together."
Demi Lovato and Max Ehrich began dating this year.
The news of their break up comes after the couple announced their engagement on Instagram in July by sharing a photo of themselves kissing on the beach.
"@maxehrich - I knew I loved you the moment I met you. It was something I can't describe to anyone who hasn't experienced it firsthand but luckily you did too.
