"If you're reading this post, you'll be aware of my passing. I've asked for this message to be made public immediately following my death.

I've had a long and fulfilling life, filled with excitement. It's been a privilege to belong to an incredible club.

Although I've been an image as a public figure for many years I've mainly enjoyed spending moments with my club brothers along with my family and my close friends.

"Please be aware that I passed away in peace after a brief fight with cancer.

However, know that at the end of the day my partner, Zorana, as well as my family and friends will be there for me.

Keep your head high, remain faithful, be freeand never lose sight of the honor of others.
