Justin was NOT in the mood last week as the couple went for counseling in Beverly Hills with Hillsong pastor Carl Lentz. Interesting, they brought along their friend and mentor who also happens to be their spiritual advisor and is, apparently, helping them with some pre-marital counseling ahead of the couple's Sept. 30 wedding date.

Justin gave us the bird going in ... and Hailey looked positively devastated on the way out. And her look had nothing to do with us -- something really emotional and difficult wen down during their session, clearly.
