Pamela Anderson - Pamela Anderson Handed Dame Vivienne Westwood A Rainforest Gift

The stars are big supporters of environmental causes and both back the Cool Earth organisation, which aims to stop logging in South American rainforests, and the Baywatch beauty splashed out on an apt present for Westwood's 2011 milestone.

When asked by a reporter for London's ES magazine to reveal the strangest gift she's ever bought someone, Anderson replied, "Seventy acres of rainforest in Brazil for Vivienne when she turned 70. It's protected by the local community so it's not in her name or mine, it's (in) theirs."
