Superstar spotting in Melbourne doesn't get much bigger than this.

Instead of a limo, Hollywood muscleman Arnold Schwarzenegger used one of the city's blue bikes to get around.

At one point, he was surrounded by young fans, posting on Instagram that he loved to see so many healthy and fit children.

Arnie, who was here for a body building show, also delighted fans at the Grand Prix.

However, senior police might be red-faced as some starstruck officers appeared to turn a blind eye to his lack of safety helmet.
