Simon Cowell is obsessed with sheep placenta facials.

The 52-year-old has turned to the beauty treatment in a bid to stay looking young and regularly attends the Lancer clinic in Beverly Hills for the facial.

A source told the Daily Mirror newspaper: ''Simon is forever trawling the health and beauty market, looking for all the latest fads.

''He's tried vitamin injections, drips, detoxes, smoothies, Botox and massages, but after reading rave reviews about placenta facials, decided he had to give them a go.

''He reckons they take years off his complexion, and give him back the shine and joie de vivre long hours and smoking take away.''

Dr. Lancer insists the treatment is completely animal friendly and says how the sheep are raised plays a huge part in the procedure.

He explained: ''These sheep are completely untouched by the modern world. It is very important they have no impurities.

''The stem cells are full of rich nutrients and the cells we harvest are amniotic, which means no harm is caused to the animals.''
