The Bros 'Rock' Disney
The Jonas Brothers' Disney Channel movie, Camp Rock premieres with 8.9 million viewers tuning in, making it the most-watched cable program this year. In the TV movie, Kevin, 20, Joe, 18 and Nick, 15, star as teen pop stars sent to a rock camp, where Joe flips over Demi Lovato's poor-girl-with-a-booming-voice character.
Kissing Selena Gomez!
Nick's ex Miley Cyrus goes public with their former romance, right when Nick moves on with fellow Disney star Selena Gomez. Although Jonas' rep denies a romance, the stars share similar first kiss stories. "Well, she's an amazing girl, and anybody would be lucky to be dating her," Nick says of Gomez.
JoBro Covers Rolling Stone
With their third album, A Little Bit Longer set to debut, the Jonas Brothers appear on their first Rolling Stone cover. The magazine says the brothers may share DNA, but are completely different, dubbing Kevin "the extrovert," Joe "the quieter Jonas, with a wild alter ego revealed onstage," and Nick the "Jonas Brothers' boss – the spokesman, the best musician, the chief songwriter." Upon its release, the album sells more than 525,000 copies to debut at No. 1 on the Billboard Top 200 album charts.
Joe Dates Taylor Swift
Although country music star Taylor Swift, 18, says Joe, is just a friend, Joe fuels "Are they an item?" rumors when he turns up at her concert. Of Swift, Jonas says, "She’s a great girl...I think anybody would love to go on a date with her." And Swift says of Joe, "He's an amazing guy and anybody would be lucky to be dating him." In October, the couple calls it quits, and Swift writes a track, "Forever and Always," inspired by their breakup.
Joe Bitten by 'Lovebug'
Wasting no time in moving on from ex-girlfriend Swift, Joe begins dating 10,000 B.C. star Camilla Belle, who stars in the Jonas Brothers music video, "Lovebug." The actress, who is three years older than Joe, is described as "a really good girl" with "a lot of the same characteristics and morals" as the middle JoBro. They split in July 2009.
'Burnin' Up' the Grammy Stage
Arguably the Grammy Awards' oddest performing pair, the Jonas Brothers & legend Stevie Wonder duet the pop trio's hit "Burnin' Up" and Wonder's classic "Superstition." Although the boys go home empty-handed (British singer Adele takes home the Best New Artist award), Nick predicted such a result prior to the ceremony. "We would love to win, [but] at the end of the day I think Adele is really amazing," he told PEOPLE. "I'd give her record of the year."
Topping the Charts
In addition to starring as a fictional band of singing brothers in their Disney sitcom JONAS, the trio takes a more personal musical step with their new album Lines, Vines and Trying Times. The album debuts atop the Billboard 200 chart, selling 247,000 copies.
Nick Going Solo
After briefly reuniting with ex Miley Cyrus, Nick steps out on his own with a new band called Nick Jonas & The Administration, which releases a new album due out Feb. 2. "This is something that can definitely co-exist with the Jonas Brothers," he says. "I've never really stood center stage before. It's going to be different but I'm looking forward to it."
Kevin Gets Hitched!
Kevin, 22, marries longtime girlfriend Danielle Deleasa, 23, at a chateau on a sprawling estate in Long Island. "We're so happy that we're finally married and we were able to share the special moment with family, friends and loved ones," the couple – who got engaged in July – tells PEOPLE.
