Danger For Demi Lovato: Friends Grow Concerned Recently Rehabbed Star ‘Can’t Be Alone’

Demi Lovato is living on her own and has once again cut everyone out of her life — leaving those closest to her worried about what’s to come for the recently rehabbed singer, RadarOnline.com learned exclusively.

“Like she did after her overdose, she has fired everyone around her very recently and got rid of new friends in a drastic measure to save herself and sobriety,” said a worried pal.

As RadarOnline.com previously reported exclusively, just days after she was hospitalized after a drug overdose that nearly killed her last July, the singer cut ties with her trusted circle of friends, as well as her longtime manager. She also severed her relationship with her rehab business partner, CAST Recovery Center founder Mike Bayer.

Meanwhile, Lovato, 26, has been struggling to sell the West Hollywood house of horrors where the overdose took place.

“She has her own apartment in the San Fernando Valley now,” said the source. “She is definitely out of her house. The apartment is her very own and she is alone.”

According to the source, her new pad is overseen by those involved with her recent rehab stint and recovery.

But those who know her best are worried that she's on her own, especially after “spending every single second” with fashion designer Henri Levy, who she allegedly met while in rehab.

Pals also fear a relapse after the troubled starlet went MIA since being trolled on Twitter for laughing at a meme that included 21 Savage who was arrested by ICE agents and later released for allegedly being in the United States illegally.

On top of all that, Lovato tweeted Feb. 23 some sad words for Disney alum and friend Ariana Grande, who’s going on her “Sweetener” tour soon. “I’m happy you’re getting to tour but can you not leave me? Thanks,” Lovato wrote.
