Selena Gomez Justin Bieber Break Up Discussed In ‘All That Matters’ Lyrics? Teen Heartthrob Talks About ‘Gut-Wrenching’ Feelings In Song

Selena Gomez and Justin Bieber have captured the attention of fans around the world for their on-off relationship, but the teen heartthrob's new "All That Matters" track might discuss his "gut-wrenching" relationship.

"The lyrics of this song are pretty self explanatory - when you fall in love with someone, that someone can make you feel whole. I feel like anyone who has been in love knows what I mean. The song conveys that being in love is one of the greatest feelings on earth. Love is all that matters," Justin Bieber wrote in his website discussing his new song.

"But the void you feel when that love goes away is gut-wrenching. I worked so hard on this song in the studio - trying to put that feeling into music was extremely important to me. I'm happy to share it with you."

Justin Bieber also released his "Heartbreaker" track on Oct. 7 as part of his Music Monday 10-week release, and the hit single's lyrics might be about his ex-girlfriend Selena Gomez. 

When Justin Bieber released the song, he tweeted about the real-life "heartbreak" that he's still going through, HollywoodLife.com reports.

Selena Gomez and Prince Royce teamed up and sang a duet performance of "Already Missing You," leaving many of her fans wondering if the song was dedicated to ex-boyfriend Justin Bieber.

The newly released track is off Royce's upcoming album 'Soy El Mismo,' which is due out on October 8, according to EntertainmentWise.com.
