The Jonas Brothers have become the latest casualty in a steady historical stream of sibling bands breaking bad. We won't know just how bad the split is until they start talking, but until then, let's revisit other doozies over the years and take a look at the events that might have led to the group's demise.
THE JONAS BROTHERS
Back story: Nick was the first to get the music bug, landing on Broadway as a mere tyke. His brothers decided to back him up, and the band was born. After their squeaky-clean songs found favor with Disney, the trio appeared on Hannah Montanaand toured with Miley Cyrus, paving the way for tweener musical Camp Rock. Once they were all grown up, the brothers split off into different paths temporarily - or so we thought.
Claim to fame: Nabbing the cover of Rolling Stone is quite the feat for a teen act. As is selling out three nights at Madison Square Garden.
The bitter end: Kevin got married. He and his wife, Danielle, even had their own "newlywed bus" while the boys were on tour. But he's since peeled off to focus on his E! reality show, Married to Jonas, and becoming a father. Nick formed a side band, Nick Jonas & the Administration. Joe embarked on a solo career. None of those projects matched the success of the band of brothers, however.
After the Jonas Brothers abruptly canceled their tour, speculation about the group's future went wild. No other details have been revealed, other than that "a deep rift" is at the center of the split. Bonnie McKee, who was supposed to open for the Jonas tour, was just as shocked as everyone else. "I had my suitcase packed, tickets bought - I was ready," she told USA TODAY. "I was angry and confused, but they're brothers, they'll probably work it out." Or not.
THE JACKSON 5
Back story: Jackie, Tito, Jermaine, Marlon and baby Michael got the party going in 1966 and took off a few years later under the wing of Motown founder Berry Gordy.
Claim to fame: Michael always was the star. His high-pitched wail was instrumental in four of their songs topping the charts in 1970 (ABC, I Want You Back, The Love You Save and I'll Be There).
The end: The siblings were one of the biggest acts of the '70s. With the massive success of Michael's solo album, Thriller, he figured he had a good thing going on his own. He was right.
Back story: A gig at Disneyland sanctioned by Walt Disney himself, followed by appearances on The Andy Williams Show, launched this expansive family in the '60s. The act started with Alan, Wayne, Merrill and Jay, and later was augmented by Jimmy as well as future superstars Donny and Marie.
Claim to fame: Not content to score big on radio and in record stores, The Osmonds also appropriated television as a medium, boasting (like The Jacksons) both a cartoon as well as the mid-'70s variety show Donny & Marie.
The end: The siblings simply grew up and apart. Some left showbiz altogether, but others went on to have their own successes, with Donny and Marie both launching their own talk shows and hoofing it on ABC's Dancing With the Stars.
NEW KIDS ON THE BLOCK
Back story: Two sets of brothers are associated with New Kids. The lineup of Donnie Wahlberg, Joey McIntyre, Danny Wood and siblings Jordan and Jonathan Knight offered a Kid to appeal to every girl; Donnie's actor brother Mark, who was turned off by the bubblegum vibe, dropped out during the band's formative stages.
Claim to fame: The group's 1988 album Hangin' Tough topped Billboard and spawned five top 10 singles.
The end: To state the obvious, they're no longer new and they're definitely not kids. In 1994, Jonathan Knight left the group, which led to the whole group disbanding. They reunited in 2008, still using the NKOTB moniker, and recently toured with 98 Degrees and Boyz II Men.
Back story: In 1991, all was well in the Gallagher household. Liam and his big brother Noel formed Oasis, which went on to be one of the most important bands in U.K. history.
Claim to fame:Wonderwall and Champagne Supernova. Enough said.
The end: Their brotherly fights are the stuff of legend. The final and most famous one involved a guitar used as a blunt object, fruit and the sound of Noel's wheels squealing as he peeled out of the parking lot, moments before the band was to go onstage at the 2009 V Festival in Paris. Soon after, Noel went public with his resignation.
THE BEE GEES
Back story: Australian brothers Robin, Maurice and Barry Gibb were a disco force to be reckoned with in the '70s. The trio's fourth album Horizontal, released in 1968, launched them to success.
Claim to fame: Forever linked to the '70s golden age of disco, they're famous for such hits as Jive Talkin', How Deep Is Your Love and Stayin' Alive. The Rock and Roll Hall of Famers have earned an estimated $200 million-plus over their 40-year career.
The end: The band split in 1969, and Robin recorded a solo album. They quickly realized they were better off together than apart, and the trio reunited a year later, eventually going on to massive Saturday Night Fever success. Of the three, only Barry is still alive.
THE ALLMAN BROTHERS
Back story: Brothers Duane and Gregg Allman are considered the architects of Southern rock.
Claim to fame: The group shot to fame on the strength of its dynamic live shows. In 1971, they turned four shows at New York's Fillmore East into a live double LP. The album reached the top 10, cementing their success.
The end: The first big blow came early, when Duane was killed in a 1971 motorcycle accident. Then there were the drugs, lots and lots of them. In Gregg's memoir, he recalls the band's rampant drug use: "The first time we walked onto the plane, 'Welcome Allman Brothers' was spelled out in cocaine on the bar," he writes. But the band's final undoing came when Gregg testified against his road manager for selling drugs. For some reason, things just weren't the same. The group would go on to split and re-form repeatedly, but has hung together well enough to earn a lifetime achievement Grammy in 2012.
Back story: Sisters Ann and Nancy Wilson initially found fame in Canada, but landed squarely on the American mainstream radar in the '70s with hits includingCrazy on You, Magic Man and Barracuda. They were inducted into the Rock and Roll Hall of Fame in April.
Claim to fame: Their raw brand of rock 'n' roll made them iconic female stars, ones that found success without taking their clothes off (hint, hint, Miley and Rihanna).
The end: Nancy dumped Ann in 1995 to focus on raising her family. But they've long since patched things up and resumed touring and recording.
KINGS OF LEON
Back story: The Followill brothers, Caleb, Jared and Nathan, grew up on the back roads of the South, going from one Pentecostal church to the next. After their parents divorced, the boys went quickly transformed from choir boys into party animals and, after recruiting their cousin Matthew, formed Kings of Leon.
Claim to fame: Their unusual upbringing was a favorite topic in just about every interview, and the group shot to fame with their boudoir rock anthem Sex on Fire.
The end: The band took a break after a series of show cancellations, twice in the middle of a gig (once because a pigeon pooped in Jared's mouth, another time when Caleb walked off stage 40 minutes into the concert). Since they went on hiatus in 2011, most of the guys have married and had kids. They're back, though, with singleSupersoaker.
