Selena Gomez delivered an emotional speech tonight at the AMAs -- it was her first public appearance since entering rehab in August to focus on her mental health.

Selena told fans, "In 2014 this stage was actually the first time I was authentically 100 percent honest with all of you. I think it’s safe to say most of you know a lot of my life whether I liked it or not. I had to stop because I had everything and I was absolutely broken inside and I kept it all together enough to where I would never let you down, but I kept it too much together to where I let myself down."

She went on: "I don’t want to see your bodies on Instagram. I want to see what’s in here. I’m so grateful to be able to share what I love with people that I love. You guys are so damn loyal but if you are broken you do not have to stay broken."

In 2014, Gomez performed "The Heart Wants What It Wants" -- a raw performance conveying her true feelings for ex-boyfriend Justin Bieber. During the number, she broke down crying, while images of Bieber played behind her, looming over her.

Meanwhile, it seems like Gomez made a big fan last night, namely Lady Gaga, who posted a snap of the two of them after the 24-year-old's powerful speech. Gaga has come forward in the past to talk about her depression, so it's no surprise that the singer was so supportive of the brunette's vulnerable and touching moment in the spotlight.
