What the heck is going on?! Justin Bieber and Hailey Baldwin were BACK at the Amen Clinic in Encino yesterday -- a clinic that brands itself a "psychiatric and brain health care" treatment center. We're worried!

With all the doctors' visits the couple's been making and with the scary trembling episodes (see HERE and HERE) Justin's had over the past year, we're concerned there's something serious going on ... but at least he's getting help?


Later Tuesday evening, Hailey got caught in the rain after a meeting in Beverly Hills and as she walked to her car in the dark, she looked somber ... maybe even sad. She's definitely standing by her man and helping him through whatever it is he's going through. In fact, Justin's mom Pattie Mallette gushed about her daughter-in-law recently, saying: "What a gift!" as the caption of a selfie with the young model kissing her cheek. And it was taken in LA yesterday, so mama Bieber's in town! Is she visiting with her son as he seeks treatment?
