Kevin Jonas Planning Debut Solo Album?

The Jonas Brothers may split say reports, as it's claimed Kevin Jonas wants to leave the band to persue a solo career.

Kevin is the oldest of the three brothers (aged 21) and he allegedly wants to move away from the trio's current younger sound. The eldest Jonas is even working on his debut solo album in secret, says an insider.

"[Kevin] wants adult fans, and he wants to sing adult music." A source tells Star magazine. "He loves his brothers but he definitely wants his solo career and won't be part of the group forever."
