Michael Jackson has broken his silence with a letter to his fans.

The singer addressed the letter to the members of his European fanclub and included news of his current activities.

Hinting that he might be releasing his first new studio album since 2001's Invincible, Jackson wrote: "I've been really busy lately...Soon I will be sharing exciting and surprising news with you from my other efforts."

The singer was rumored to be working with Black Eyes Peas frontman Will.I.Am in a studio in Ireland last year.

According to a printed letter leaked by fan site Mjeurope.eu, Jackson wrote: "I've been really busy lately...Your continued love and support means so much to me. I really love and appreciate you all...from the bottom of my heart."
