The project was re-released as Nick Jonas X2 in 2015.
The release helped provide Jonas with a new public image, earning him the title of a sex symbol.
The project debuted at the top spot on the Billboard 200, boasting first week sales of 247,000 copies.
The band cancelled their highly anticipated tour in October only days before it was set to begin, citing a "deep rift within the band" over "creative differences", leading to speculation that the band would be parting ways.
The band's third studio album, A Little Bit Longer (2008), saw continued commercial success for the group; the album's lead single hit the top five on the Billboard Hot 100 chart.
The band became prominent figures on the Disney Channel during this time, gaining a large following through the network, later appearing in their widely successful musical television film Camp Rock (2008).
From 2009 to 2010, Jonas and his brothers starred on the Disney Channel series Jonas.
After the Jonas Brothers confirmed a hiatus, Nick formed a new band known as Nick Jonas & the Administration, who released the album Who I Am in 2010 to moderate commercial success.
Thereafter, Jonas opted to focus on work in theater, and also had a recurring role on the television series Smash.
The Jonas Brothers briefly reunited in 2013, though officially parted ways due to creative differences.
The band achieved further success with their third studio album, A Little Bit Longer (2008), which became their first to debut at number one on the Billboard 200 chart; the project sold over 525,000 in its first week of release.
