Demi Lovato reportedly fired her sober coach just three weeks before her suspected overdose.



The 25-year-old singer is currently recuperating in hospital after she was found unconscious at her home in Los Angeles after taking a mystery substance but, although she's managed to keep her break in sobriety under wraps until now, it's believed she began to slip off the straight and narrow at the beginning of the year when she started rowing with her counsellor Mike Bayer.



A source told The Sun Online: "She fired him a few weeks ago - they had a big argument and then they unfollowed each other on social media. It has been very ugly and messy as this guy was like 'her rock' that she leaned on after she and Wilmer broke up.”



It's believed the 'Sorry Not Sorry' hitmaker hired Mike after she first sought help in rehab for her addictions back in 2010.
