Demi Lovato and Nick Jonas have launched a record label together.

The 'Heart Attack' singer revealed she will join her fellow former Disney star Nick Jonas in launching Safehouse Records with manager Phil McIntyre and she gushed on Instagram about the people behind the scenes who helped make it happen.

Below a picture on of her signing documents, the pop babe wrote, ''A day I will never forget,'' while another post explained she is, ''So excited for the future''.

The 22-year-old star used the opportunity to praise her manager Phil for being an ''extremely important person'' in her life, crediting him with saving her career by helping her get sober.

Following the announcement, she said: ''This man not only believed in me when I was 15 and made my entire career happen, but he fought so f***ing hard to get me sober. He is one of the very few people who LITERALLY saved. my. life. I don't think I'd be alive without him for many different reasons.

''So many other managers out there will try to become the artists themselves by putting their name out there just as much as their artist by doing interviews of photoshoots... But Phil is one of the mist HUMBLE and hard working people I know. I can't wait for our future together Phil. I'm so grateful for you. (sic)''

Demi - whose last eponymous record was released in 2013 - will release her as-yet untitled fifth studio collection through the label, which promises to ''put artists in control''.

A statement from Nick and Phil released to Gossip Cop read: ''Our focus at Safehouse Records is to put artists in control of their art while providing them the best tools to manage their careers ... through our partnership with Island Records they will also have access to the best marketing and promotion available.''
