Joe Jonas has slammed rumours he has a substance abuse problem.

The 24-year-old singer is upset about allegations that he and his girlfriend, Blanda Eggenschwiler's constant partying led to the breakdown of his band, The Jonas Brothers, with his siblings Nick and Kevin, and speculation he recently sought treatment in rehab for drug abuse.

The 'Pom Poms' hitmaker told ''It's ridiculous! We're not saying anything for two or three weeks and I'm a drug addict!

''It's obviously not true. I've never touched heroin in my life. Neither has my girlfriend. It's hilarious to me, but also frustrating as well. It p***ed me off when it's about my girl and even about myself.

''I was walking down the street and people are asking me if they can give me a hug and how rehab is. I'm like, 'You tell me because I've never been.' ''

The brothers decided to call it quits after Nick, 21, told them he had doubts about the band and Joe is eager to set the record straight after taking a few weeks to deal with the split.

He said: ''We all had to deal with it in our own way. I needed time to clear my head.''

The heartthrob, who previously dated Taylor Swift and Ashley Greene, is now looking forward to the future.

He said: ''I'm genuinely excited.''
