Selena Gomez, who has been on a month-long break from the limelight to focus on her "health and happiness", has reportedly entered a rehab facility in Tennessee. Multiple sources allegedly told Us Weekly magazine that the singer, who cancelled her revival tour mid-way to deal with the side-effects of Lupus disease, is now seeking professional help to "focus on her mental health".

According to the report, "Selena is dealing with lupus, but this break is to focus on her mental health. She can go to a very dark place." Describing the facility that is just outside of Nashville, a source told the magazine that it is a "private and quiet place," but "super intense."

Earlier the Kill Em With Kindness hitmaker was spotted in Tennessee as she stopped by the Texas Roadhouse in Alcoa for a late lunch. According to an eyewitness, Gomez appeared to be enjoying herself as she clicked photographs with her fans. "She couldn't have been more gracious to everyone and to the fans and was more than happy to take pictures with whoever," said the onlooker.

However, this is not the first time that the 24-year-old songstress has checked into a rehab facility, the Us magazine report adds. Previously, Gomez was reported to have sought professional help in 2014, a year after she was diagnosed with the chronic autoimmune disease. Gossip website reports even claim that the pop star has stopped working on any new music ever since she announced her break on 30 August.

"She was supposed to be recording, but she hasn't told anyone when she'll be back in studio," a music industry source told the magazine.

When Gomez had cancelled her music tour in August to take a break from her career and the media attention, she had thanked all her fans for their support as she copes with "anxiety, panic attacks and depression".

"I want to be proactive and focus on maintaining my health and happiness and have decided that the best way forward is to take some time off. Thank you to all my fans for your support. You know how special you are to me, but I need to face this head on to ensure I am doing everything possible to be my best. I know I am not alone by sharing this, I hope others will be encouraged to address their own issues," she explained.

IBTimes UK has reached out to Gomez's representatives for a comment and is awaiting a response.
