Miley Cyrus celebrated turning 20 on Friday (23Nov12) with a new pig.

Activists at People for the Ethical Treatment of Animals (Peta) adopted the rescued pig, called Nora, in Miley's name as she transitioned from a teenager to her 20s.

Peta bosses snapped up the odd gift to pay tribute to animal lover Cyrus' efforts to make the world a better place for creatures.

Executive Vice President Tracy Reiman says, "Peta knew that sponsoring a rescued pig was the perfect birthday present for a young woman who spends so much time encouraging others to help animals.

"From promoting animal adoption to speaking up for cows who suffer on dairy farms, Miley never stops letting her millions of fans know what they can do to make the world a kinder place."
