Sibling rivalry, it happens to the best of us. Personalities clash and even blood can't change that.
Take a look at some of the most healthy and the most dysfunctional sibling bands of all time:
Haim is a three-piece band of sisters Este, Danielle, and Alana. The bandmates, roommates, and best friends swept to the top of the music industry with their smash hit "The Wire" last year. They rarely fight, and when they do—it's over clothes.
The Nervo twins are Miriam and Olivia Nervo, who have captured the hearts of dance music fanatics across the globe. The identical twin sisters have been writing music together professionally for nearly ten years. The only disagreements the two have are in the studio, and they don't let it permeate into their personal lives.
The UK brother duo is one of the biggest dance music acts of the decade. With all the fame and popularity the brothers have recently garnered, they have revealed that there is no sibling rivalry between them. In fact, they're good friends due to the amount of time they spend together.
Ten years ago, the JoBros were the hottest Disney-created boy band. After four studio albums, the bros called it quits because of issues with music and the direction of the band. Although Nick, Joe, and Kevin have professional disagreements, they still speak and remain close siblings.
Kings of Leon
Kings of Leon is an award-winning band that consists of Followill brothers Caleb, Nathan, Jared, and their cousin Matthew. Throughout the years, the band's blowouts have gotten crazier and crazier. In 2007, one boozy night ended with Nathan dislocating Caleb's shoulder and stabbing his bed with a knife.
This brother band may be more famous for their rivalry than their music. Besides being the longest UK chart-topping band of all time, the Gallagher brothers are notorious enemies who refuse to speak to each other. The band broke up after a huge backstage fight in 2009, when Liam attacked Noel with a guitar and almost took his face off.
The most dysfunctional sibling band on our list is The Kinks, who hold a spot in the Rock and Roll Hall of Fame. Such prestige still won't bring the bros back together. Ray and Dave Davies have been feuding for over fifty years, and publicly shame each other to the press, calling one another "a**holes" and "toxic."
