Demi Lovato appears to have parted ways with some of her closest friends.

The singer, who almost died of a drug overdose in July and just came out of rehab, has unfollowed Selena Gomez, Nick Jonas and Iggy Azalea on Instagram.

The move comes as a surprise, since both Selena and Iggy had supportive things to say about Lovato following the news of her drug overdose and hospitalisation.

Unfollowing Jonas is also a shock, since she’s still following his brothers Joe and Kevin.

A source told Entertainment Tonight the Sober singer is trying to “avoid any difficult relationships”.

“She needs to surround herself with those that support her goals and to stay away from any negativity,’ an insider close to Demi told Entertainment Tonight.

“Demi has come a very long way. She’s grown emotionally and matured a great deal through this process.

“She realises there is no quick fix and has accepted the fact she needs to take this one day at a time. She still has a sober companion and she has built a very strong support group.”

Lovato, 26, was found unconscious at her Hollywood Hills home by her assistant back in July, hours after consuming a dangerous cocktail of illegal drugs.

Breaking her silence in August, the singer said she has “always been transparent about my journey with addiction.”

“What I’ve learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet.”
