Michael Jackson - Chimp

The 'Billie Jean' hitmaker famously kept a pet chimpanzee called Bubbles who stayed at his Neverland home.

Bubbles slept in a crib in the late pop star's bedroom and even used Jackson's toilet.

The chimp was sent to a California animal trainer in 2003 as he had become too aggressive to be kept as a pet.

Bubbles now resides in Florida and celebrated his 40th birthday last year.
