You'd never know it listening to their duet, "Lonely Road," but Jelly Roll and rocker/rapper MGK once had some pretty serious beef.

It's true: Early on in his career as a rapper, Jelly even put out a song called "Malibu's Most Wanted" that appeared to be an MGK diss track. Of course, they've since come around, and are now such close friends that they even co-starred in the "Lonely Road" music video together, along with Jelly's wife Bunnie Xo and MGK's partner Megan Fox.

In a new Spotify podcast episode called "Jelly Roll: Countdown to Beautifully Broken,"  which celebrates the upcoming October release of Jelly's Beautifully Broken album, Jelly and MKG both spoke about their one-time feud and explained why they hated each other so much to begin with.

"It is so funny how much I love you now, because God, I hated you so much back then," MGK tells Jelly in one portion of the episode.

Jelly doesn't hold it against him. In fact, he thinks he deserved MGK's disdain. "I was just a little spiteful, bitter f--king dude," he says, breaking out into laughter.

"I explain this to people -- they don't understand the concept because of our age now. Whenever I talk to my daughter, I'm like, 'You gotta understand, there was only, like, seven white rappers on Earth at this time,'" Jelly continues. "So it was so competitive when you was in that pool. We were kind of automatically forced against each other anyways."

"For sure," MGK agrees. "You were bred to hate each other."

Jelly also admits that a little bit of jealousy might've played into his dislike for MGK. "You were just skinny and handsome," he continues. "I was just a hater. You know what I'm saying? I was just a hater, dude!

"It's hard to grow up in front of the whole world," Jelly admits, as the two men crack up.

Jelly has often spoken about how far he's come in his personal evolution over the last several years, including laying to rest several feuds with those in his personal and musical circles.

Last December, he opened up about an instance where he once tried to fight The Black Keys' Patrick Carney because he thought they were laughing at him and his friend, fellow musician Yelawolf, at a show.

"Man, God softened my heart," he said in hindsight. "Looking back at that kid, I kinda laugh...I was so entitled and so angry, and everything was about me. I thought they were joking and laughing at us 'cause I was used to being in that situation. It was all about ego, man."

Jelly's Beautifully Broken album is due out on Oct. 11. He's currently in the midst of a headlining tour with the same name.
