Bieber announced the song on Twitter, writing, "A new song with @poobear is on my official page "Hard2FaceReality", reports eonline.com.
The 20-year-old's new track's lyrics said: "Sometimes it's hard to face reality, even though you might get mad at me. Don't be afraid to stand alone, Don't be afraid to stand outside the door alone, I know it's hard away from home, it ain't easy all alone."
Meanwhile, Bieber spent the weekend in New York and even shared a photo on Instagram from Central Park, writing: "Was gonna wait to go to Central Park for when I proposed to my future wife but s-sometimes things change. I'll think of something more romantic."
He also shared a picture of him surrounded by fans with a supportive message: "When people try and break you, I got your back, just like you got mine."
