EXCLUSIVE: Justin Bieber Reveals Why He's Crying So Much Lately, Where He Sees Himself in 10 Years

It's been an emotional year for the Biebs.

"I've been having a lot of cries lately," Justin Bieber admits in an interview with Entertainment Tonight.

He can say that again.

It all started with the MTV Video Music Awards in August, when the 21-year-old broke down on-stage immediately following his performance of "Where Are You Now?" More recently, the Biebs burst into tears while singing "I'll Show You" at his album launch celebration concert at Staples Center in Los Angeles on Friday, Nov. 13.

"Why am I crying so hard?" he asked himself. "I gotta get it together, Justin!"

Sitting down with ET special correspondent Elvis Duran, Bieber opens up about this "emotional time" in his life.

"Good cries, bad cries, just all around being emotional," he said. "I think it just shows how much I care. You know, I care about this project so much and I've put my heart and soul into it, spent the last three or four years making it. So it's been exciting, it's been an amazing rollercoaster ride. Sometimes good days, sometimes bad days, but overall it's been pretty awesome."

Bieber released his highly anticipated studio album Purpose on Friday, which earned the star his first-ever No. 1 single -- though the album's chart performance remains to be seen. Purpose is in a race for No. 1 against One Direction's Made in the A.M., which was released the same day.

Purpose marks something of a comeback for Bieber, who has been plagued with heartbreak and scandal in recent years. Within the last year, Bieber has worked tirelessly to turn his image around.

"I'm stubborn and I've always been really stubborn," he confessed. "I think if I would have just known I could have been myself, but I don't think I knew my self worth enough. I think that comes in time."

The "Sorry" singer admits he's still figuring out who he is, but has his eye on the future. Bieber said he hopes to "have a family -- wife, kids" in the next 10 years, and an "indoor basketball court and indoor pool."

As for the music he'll still be making...

"I can't really predict that," he said. "Music can go completely left. And I wanna always be doing what's popular, 'cause I'm a pop music artist. Doesn't mean I'm going to do what everyone else is doing, but I'm going to do what's relevant. Always."
