Gomez has reportedly had her own struggles with substance abuse and left rehab for the third time in November 2016—so hanging out with an open drug user may not bode well for her recovery. Though Gomez and her camp insist she was seeking treatment for emotional and psychological issues stemming from her lupus diagnosis, some insiders claim she had substance abuse problems as well.

A source told Radar Online after her first rehab stint in early 2014, "Her friends and family became increasingly worried that there might be a serious problem...The partying was, at times, wild. They wanted to help her—and they very much encouraged her to go to rehab." Star reported at the time that Gomez often smoked weed with her on-again-off-again ex Justin Bieber. An insider told Radar Online that she was "experimenting with marijuana and prescription drugs, including Xanax and Ambien."

Just before going to rehab again in summer 2016, a source told In Touch Weekly, "Selena's major source of unhappiness right now is twofold. She's realizing that the career she so desperately wanted as a child doesn't fulfill her anymore. And then there's her inability to date a nice, normal guy."

Sources said her most recent rehabilitation seems to be sticking...for now. "Since Selena got out of rehab, she has been cutting out all of the bad influences in her life," a source told Radar Online in December 2016. "Selena is sober now, and she is doing everything right. She is continuing to see a therapist and surround herself with positive influences." Based on his own admissions, was Tesfaye really a positive influence?
