The Jonas Brothers

Ten years ago, vows of chastity were all the rage.

From Katy Perry to Robin Thicke, look back on some of celebrities' worst (and harshest) musical spars.

This supposed Instagram comeback seems to say as much.

Joe also opened up about not being able to sing about sex while in his former band.

Kevin Jonas not only opened up about feeling "depressed" following the break up of the Jonas Brothers, but he also offered up some advice to former One Direction member Zayn Malik in dealing with leaving the band.

The Jonas Brothers shocked fans when they famously canceled their tour two days before its start date and then officially announced their break up shortly after, but Kevin is finally ready to dish on the split.

Although he's known for his role in the Jonas Brothers, Kevin recently launched his newest project -- an app called Yood.

Ah, 'Camp Rock.' It's hard to believe that it's been six years since the Jonas Brothers and Demi Lovato won our hearts in that amazing Disney Channel summer camp musical.

As a member of the former Jonas Brothers, Kevin Jonas has lived a pretty amazing life at just 26-years-old. But he’s now embarking on his craziest adventure yet — being a dad!

The Jonas Brothers made the rounds on Z100 (radio) and the 'TODAY' show (TV) on Aug. 21, since they have a lot going on and much to discuss. They are in the studio. They have a reality show. They have a Radio City Music Hall concert set for October. It's good to be (a) Jonas!
